If Mourinho was to axe 10 players from that squad, he would have to sign an incredible seven players this summer to get up to 23.
Luke Shaw who's relationship with Jose Mourinho has become even more strenuous this week is set to end his four year stay at the club this summer.
Shaw broke his leg in Manchester United's 2-1 loss to Dutch giants PSV Eindhoven in the Champions League in September 2015. Nearly two and a half years on, surely that injury can now be put aside and cannot be held as the reason the player has failed to progress.
Mourinho was keen to create a division between the Spanish global players at Madrid and those at Barcelona, which Casillas and Sergio Ramos strongly opposed. It is hard to argue that either player is more talented than the Manchester United ace.
"I felt his head was not in the right place to make the sacrifices and decisions that are necessary at that age."
"I've got to play well at United to get that recognition, and now I've had that in this call-up, I've got to impress".
Yes injuries have blighted the player's career to date but they alone can not be blamed for the lack of progression the player has made in his short career to date.
Asked if Shaw can fight his way back into Mourinho's plans, Young said: "Yes, of course".
It is a odd situation, though, as when Shaw joined the Manchester outfit he was ranked as one of the brightest young players in Europe in his position. Nothing seems to be working.
"I feel like I am playing with confidence, I have done all season", Young said.
Mourinho is an easy target at the moment and all talk of bullying the player is nonsense. But we're down to play football. "I sit in this chair with Real Madrid, Manchester United out!" remarked Mourinho in his post-match press conference. Left-back has been a problem position this season, as first choice Leighton Baines has missed a chunk of the season through injury and they lacked cover in the position.
Perhaps he should use the opportunity to decide what he wants from his career.
