Romelu Lukaku is considering his future at Manchester United.

The Sun says the £75million Belgian striker has joined fellow big-money signings Paul Pogba and Alexis Sanchez in growing frustrated under boss Jose Mourinho.

Lukaku, 25, would weigh up a move away from Old Trafford if his spell out of the team continues.

The new player crisis at United comes as Mourinho's agent Jorge Mendes issued a statement claiming the Special One is “fully committed" to the club.

It's claimed United's top brass want to replace him with Spurs boss Mauricio Pochettino next summer.

Mourinho is also the bookies' favourite to become the next Prem manager to be axed.
