Manchester United’s Amad Diallo celebrates after the match with Michael Carrick
When Thomas Tuchel was parachuted into Chelsea mid-season four years ago, he actually arrived by plane. And on it, he devised the tactics that propelled a team who had languished in mid-table in the Premier League to Champions League glory. It involved a change of shape, to a 3-4-3 formation.
When Michael Carrick was taken from the relative obscurity of being a former Middlesbrough manager and given the Manchester United post for the rest of the campaign, the situation was different; the solution too. Carrick veered away from a 3-4-3 system, the easiest and most popular thing he could do.
