Manchester United face competition for Benfica star Angel di Maria.

The Daily Mail says Inter Milan boss Jose Mourinho will battle Manchester United and Chelsea for £15million-rated Di Maria.

United have offered £12m plus winger Nani for the Argentinian, while Chelsea sporting director Frank Arnesen has been to see him in action.

But Inter also watched him on Sunday and are now preparing an offer.

Benfica president Luis Filipe Vieira is determined to keep him, but says they will not stand in his way if a rival club meets his release clause in his contract.

Vieira said: "The player will be allowed to leave in the transfer window if another club pays the clause in his contract. We need to know what the offer will be and then make a decision on which is the best value for the club."
