Darren Cahill has delivered his first post since he and Jannik Sinner conspired to win this year’s Wimbledon title.

It was a mesmeric run from the 23-year-old, who was forced to beat both Novak Djokovic and Carlos Alcaraz en route to the title.

However, such is his unrelenting quality, he brushed both aside with relative ease, showcasing the furious, powerful hitting and a work rate that nobody on tour can compete with when at its best.

He has now won two of this year’s three Grand Slam titles, and is the overwhelming favourite to win the fourth in New York later this year too.

If this is to be Cahill’s last year by Jannik Sinner’s side, it’s certainly on track to be a generational one.

And, the two are clearly loving life together despite all the turmoil suffered in recent years, including a three-month suspension from tennis for a doping-related incident.

However, that enforced absence from tennis has arguably added to just how impressive Sinner’s seamless return has been, easily slotting back in and proving why he is very much still the world’s best player.

Cahill has now taken to Instagram to offer a series of photos documenting their last few weeks at Wimbledon, with a short message of congratulations to the four-time Grand Slam champion too.

The relationship he shares with his student is a wholesome one, with a father-son dynamic emerging from this tennis machine they have created.

Jannik Sinner will desperately want to keep Darren Cahill on board

Although it has already been confirmed that Cahill will leave Sinner’s team at the end of 2025, there have been murmurs suggesting otherwise since the Italian has returned from his three-month ban.

After all, the way in which he has rediscovered his form, arguably reaching even newer heights, has shocked everyone, likely including his coach.

This physical and technical freak of nature was just one point away from completing the French Open and Wimbledon double, a feat very few have ever accomplished, all whilst the earlier event marked just his second tournament back after that spell away from the sport.

This has clearly sparked great debate within Cahill, as some are now suggesting he’s not done completely with Sinner.

In fact, there are some suggestions that he would be willing to continue but in a reduced capacity, only flying out to specific tournaments when really needed.

Whatever it takes to keep Cahill in his camp, Sinner should do it. He’s been so influential, and the two are on track to create a legendary dynasty together in tennis.
