This is still one of the more bizarre ones on this list, that no one has ever really been able to work out. Mata was quite brilliant for Chelsea in his first two seasons with the club, winning their Player of the Year award on both occasions.
He was a huge part of the side who won the Champions League in 2012, and was almost irreplaceable in their team. That was at least until Mourinho came along.
From the first moment, there were problems. He didn’t make it into Mourinho’s side at the start of the season, and he was never able to change his manager’s mind about him. Mourinho was unhappy with Mata’s inability to track back in the same way some of his other players did, and he felt it often left them vulnerable at the back.
He was sold to Manchester United just six months after Mourinho returned to Chelsea. Ironically, Mourinho took over at Old Trafford in 2016, and Mata currently finds himself out of the United side.
