Disagree. Theoretically he was played on the right, but it was always clear that he was the factual number 10 in the team with license to do his things. He just doesn't have the ability or mindset to control the play for a big club like Manchester United.
And I'm not saying this with a smile on my face because I wanted him to be a success here, like any other player but it's become very clear to me that Chelsea absolutely robbed us of 37 million pounds. Not even Chinese clubs will pay that money for Mata now. Just shows how brainless we have been in our transfers in the last 5 years.
