The stand-off between Ten Hag and Sancho lasted four months, before Sancho joined Dortmund on loan for the remainder of the season and helped them reach the Champions League final.
But they could not afford to keep him and, although United sporting director Dan Ashworth was credited with brokering the truce that allowed Sancho to join up with United in the pre-season of 2024, it was a temporary situation, which Chelsea seemed to solve by agreeing a loan that committed them to a permanent transfer at the end of the season.
Yet, after five goals in 41 appearances, Chelsea preferred to pay a £5m penalty to send Sancho back to Old Trafford.
This time, there was no olive branch. Sancho was placed in Ruben Amorim’s ‘bomb squad’ and had to train away from the first team until he joined Villa on 1 September.
Now United have decided not to trigger the one-year option.
At 25, Sancho still has a lot to offer. There were glimpses of quality during his time at Villa, but he was only introduced off the bench nine minutes from the end of the Europa League final victory over Freiburg on 20 May.
“Seeing Jadon close up, technically, he’s got an awful lot of ability,” said current United interim head coach Michael Carrick when he was asked about Sancho in March.
Carrick worked with Sancho as part of Solskjaer’s backroom team and managed him for three games during his short stint in charge after the Norwegian’s dismissal.
“In and around the box; his ball carrying; his little plays; the connections; his creativity; the way he handles the ball – he’s got natural ability,” said Carrick.
“He’s always had it all the way coming through. That’s one part of football.
“But – and I’m not talking about Jadon individually on this – it is just how it is and how it should be.
“You can’t just assume it’s all going to be smooth. It’s proven that it’s not always like that.
“You’ve got to find a way through it. If you are playing in a good team with good players and a good squad and depth, that’s part of the challenge to stay at the top.”
