Angel Di Maria has launched an extraordinary attack on his former club Manchester United, claiming he didnt "give a f***" about taking the clubs famous No.7 shirt number. The Red Devils shelled out a club-record £59.7million fee to sign the winger from Real Madrid in August 2014. Di Maria proved to be a sound addition at first, scoring a memorable goal against Leicester City and registering 10 assists and three goals in 22 appearances. But the playmaker struggled to adapt to life in Manchester and had trouble settling in with his team-mates after failing to improve his English.His future became uncertain after his house was burgled while he was playing for the club and when Paris Saint-Germain offered £45m to sign the winger, he pushed to leave Old Trafford.Angel Di Maria poses with Louis van Gaal and the No.7 shirt at Manchester UnitedNow Di Maria has lifted the lid on his short spell in England and in doing so chose to aim several jibes at his former employers, claiming that the No.7 shirt given to him worn by club legends such as Eric Cantona and David Beckham had no special meaning.
