Chelsea are champions of the world.

That may sound strange, even to many fans, at the end of a season in which Enzo Maresca’s team finished fourth in the Premier League and lifted UEFA’s third-tier club competition, the Conference League.

But there can be no diminishing the emphatic manner of their 3-0 victory over recently-crowned European champions Paris Saint-Germain at MetLife Stadium on Sunday. Chelsea were deserving winners of Gianni Infantino’s inaugural expanded FIFA Club World Cup, netting $114.6m (£84.5m) in prize money in the process.

That triumph, and that financial windfall, opens up a world of possibilities. It also raises a number of questions about what happens next at Chelsea — questions that The Athletic will attempt to answer.

What will they do with the cash?

Firstly, the players and coaching staff will all receive a sizeable bonus equivalent to that which would have been awarded had Chelsea won the Champions League. This is all in keeping with Chelsea’s policy of handing out incentivised contracts rewarding success.

The sudden injection of extra revenue has made no difference to Chelsea’s transfer plans, though. They are already happy with the business done so far this summer in adding three players to their attack in Liam Delap, Joao Pedro and Jamie Gittens.

More arrivals could be made, but they will be dependent upon player departures. That is the main focus for the time being — the plan is to smooth more exits than incomings before the end of the window. The club have a number of squad members who are not part of their long-term plans and are also looking to go elsewhere. Those on the list include Raheem Sterling, Ben Chilwell, Joao Felix, Renato Veiga, Armando Broja, Lesley Ugochukwu and Axel Disasi.

Among many possible remaining transfer targets are Manchester United’s Alejandro Garnacho and Aston Villa’s Morgan Rogers. They have also made an enquiry for Ajax defender Jorrel Hato.

The price of playing a full month of competitive football in the United States is that Chelsea will not have a normal full pre-season.

Those who competed at the tournament have now been given three weeks off, which means they will not return to the training ground at Cobham until the first week of August.

Estevao Willian, who agreed to join from Palmeiras last year, and Gittens (who signed from Borussia Dortmund) may report earlier, given their teams were knocked out in the quarter-finals of the Club World Cup.

It is customary these days for footballers to do their own training while away on vacation to stay in shape, but it is obviously not the same as working together with the entire group.

Chelsea saw the Club World Cup as part of their pre-season preparations. It is one of the reasons they wanted to secure Delap, Joao Pedro and Gittens early so they could start to integrate with their new team-mates. Maresca also worked on new tactics and systems during the competition with next season in mind.

But Chelsea have just two friendlies, against Bayer Leverkusen and Milan, before their opening Premier League game versus Crystal Palace.

There are players who have been training at Cobham for 10 days now, but they are returning loanees who are expected to be sold.

Todd Boehly has been the only one to break the public silence on Chelsea’s ownership dynamic since his tensions with majority shareholders Clearlake Capital spilled out last September, giving semi-regular interviews at various business conferences and, most recently, a short exclusive conversation with talkSPORT.

But even then, what he did not say was as illuminating as the words he chose.

“I think the form that you’ve seen is everything we hoped when we were putting this together with (co-sporting directors) Laurence (Stewart) and Paul (Winstanley),” Boehly told talkSPORT.

“Behdad (Eghbali) and I couldn’t be more grateful for the success that they’ve had, and for all Chelsea fans everywhere. We’re just so thrilled, and thank you for sticking with us. We’re really excited about what the future holds.”

Boehly did not shed any light on the health of his relationship with Clearlake co-founder Eghbali, the state of which was a prompt for both parties to explore options to buy out the other last year and was detailed by The Athletic.

It was a surprise to see Boehly walking out alongside United States President Donald Trump as Chelsea’s representative in the Club World Cup medal ceremony on Sunday, given that it is Eghbali who remains the most actively engaged owner in the club’s daily operations and the most visible member of ownership at most games.

The relationship is described by sources with knowledge of the situation as professional, but the issues that arose last year have not gone away. While Chelsea are functioning successfully within the status quo, it is hard to escape the conclusion that something has to give as the club seek to navigate big decisions ahead — chiefly how best to proceed with a stadium plan.

Gaining clarity on when — and where — Chelsea might be playing in a new stadium would be an even bigger milestone for the club than winning the Club World Cup.

As detailed by The Athletic in March, a stand-by-stand renovation of Stamford Bridge has been discounted due to the costs and disruption involved in such a process, as well as the limited ability to improve match-day experience or capacity. That leaves only two options: demolishing Chelsea’s historic home and building an entirely new arena on the site, or acquiring the large plot of land that formerly housed the Earls Court Exhibition Centre and building there.

Staying and redeveloping Stamford Bridge to the specifications that Clearlake and Boehly are looking for is exceptionally complicated, to the point of potentially being unfeasible.

It would be logistically far easier to build a modern super-stadium on the much larger Earls Court site, but that land must be purchased from property developer Delancey, Transport for London (TfL), the London Borough of Hammersmith & Fulham (LBHF) and the Royal Borough of Kensington and Chelsea (RBKC).

That is unlikely to be simple, or cheap, and then there is the fact that any permanent move away from Stamford Bridge would require 76 per cent approval in a vote of Chelsea Pitch Owners (CPO), the supporter group that owns the freehold to the club’s current home. Roman Abramovich failed to clear that dauntingly high bar when attempting to buy the freehold in 2011.

Chelsea are currently caught between two unenviable stadium options, and are trying to strike a balance between thorough due diligence and a sense of urgency to avoid the club falling behind the Premier League rivals who can boast bigger, newer stadiums.

In the meantime, Delancey’s own big plans for the Earls Court land are moving forward: a decision on planning approval for their sprawling proposed mixed-use development that would include 4,000 new homes is expected from LBHF and RBKC at the end of July.

How close are they to securing a front-of-shirt sponsor?

Chelsea are talking to up to 10 major brands and are looking at signing a long-term deal worth £60million a year.

They feel in a strong position to generate such a sum for a number of reasons. It clearly helps that Chelsea are back in the Champions League and have also just won the Club World Cup. But the club believes firms will also want to be associated with the youngest team in the Premier League, a side crammed with exciting players like Cole Palmer, Estevao and Moises Caicedo.

Chelsea have the potential to be one of the best sides for several seasons and being the only club without a front-of-shirt sponsor right now means they do not face competition from rival clubs.

They have received bids over the past 12 months that were for much lower sums and/or for a short length of time. A conscious decision was made to wait in case their argument for a greater price improved courtesy of a return to the Champions League. That decision appears to have paid off. There is confidence a new partnership will be agreed.

The question has certainly been asked outside Stamford Bridge in the immediate aftermath of the team lifting the Club World Cup.

But, internally, no one is getting carried away by such talk or overexcited by their achievements over the last few months.

Chelsea won the UEFA Conference League and qualified for the Champions League for the first time under the Todd Boehly-Clearlake consortium via a fourth-place Premier League finish. The overriding message, though, is to stay humble. There is a recognition that a number of leading clubs — including defending champions Liverpool, Manchester City and Arsenal — are doing good business during the transfer window. The competition is only going to be stronger next term.

The only expectation for next season is to qualify for the Champions League via a top four/five finish again and to go on good runs in the cup competitions they are involved in — the Champions League, FA Cup and Carabao Cup.

Will they defend their Club World Cup trophy in four years’ time?

FIFA are yet to adopt a definitive position on whether winning the Club World Cup guarantees entry into the next edition of the tournament. That is not hugely surprising, given how hastily this summer’s inaugural expanded competition was arranged in the U.S..

The answer may depend on where football’s governing body looks to for precedent. World Cup winners have not been given automatic passage into the next edition of the tournament since France in 2002, but winning UEFA’s flagship Champions League grants qualification for the league phase of the following season’s competition.

As things stand, there is no mechanism for Chelsea to be certain that they will be Club World Cup participants in 2029. But as FIFA demonstrated with a convenient interpretation of their entry criteria to ensure the presence of Lionel Messi and Inter Miami at this summer’s tournament, the entry rules of such a new competition are not fixed.

It is possible that, by 2029, the Club World Cup may feature even more clubs. It is also possible that Chelsea could render this particular conversation moot by winning the Champions League at some point in the next four years, or by qualifying on merit via another means.

In any case, you can be confident that Chelsea will lobby to be included again as defending champions — they would be foolish not to.
