United Have Bought A Very Good Player In Mata, Claims City Rival Pellegrini
Manuel Pelegrini believes Juan Mata can transform Manchester United's season.
The Spaniard signed for City's rivals over the weekend for �37.1million and goes straight into their squad to face Cardiff City on Tuesday.
And while David Moyes' side are six points behind the top four after a fairly disastrous season, Mata can prove the difference.
