United are aiming to sign Mata this week.
âI like Juan Mata because he is a match-winner on his day,â McIlroy told the Manchester Evening News.
âHe is a little bit different to what United have at the moment in midfield and is just what we need.
âThe one thing people are asking is why is a manager of Jose Mourinhoâs calibre and success getting rid of him?
âWhy does he not fancy him in his team when he has been so popular and successful in Chelseaâs midfield in the past?
âSome reckon it is because you have to build a team around him because he cannot do the tracking back and work that Jose wants.
âBut if you have to build a team around him why not? If others have to do a bit more work to accommodate him, what is wrong with that? Sometimes you have to go for a player some might regard as a âluxuryâ.
âIt all depends on to what extent you âcarryâ a player. If he is a bit special and wins you matches then sometimes you can afford to have that kind of a player in your team.â
