Manchester United winger Nani has had an ugly confrontation with teammate Davide Petrucci, it has been revealed.The Sun says the Portuguese winger, 25, initially had a verbal row with reserve team midfielder Petrucci, 20, after a training-ground tackle at the club's Carrington centre.

United's players had to step in to separate the pair after the confrontation later escalated and Nani allegedly threw a punch at Petrucci.

The confrontation will not help Nani's career at Old Trafford. He is already frustrated at not being offered a new contract to improve his current deal.

Nani is on £90,000 a week. He was looking at a new four-year deal worth £130,000 a week but the United board rejected those demands to leave the player in limbo.
