Manchester United face having to hand Marcus Rashford crazy money to hold onto the striker.

The Sun says United may be forced to pay Rashford £350,000 a week to fend off Real Madrid and Barcelona.

The striker is negotiating with Old Trafford bosses as he enters the final 12 months of his contract.

A source said: “Marcus is United through and through and doesn't want to leave.

“But it wouldn't be a hardship playing for either of the big two in Spain if they can't agree a deal.

“Lots of footballers sign deals on the basis of not only what their worth is now but what they will be worth in one, two or three years.

“He's happy under Ole and has cemented his role as the main striker but if Sanchez can get £505,000 a week, then Marcus knows the money is there.

“If the likes of Marcus and De Gea sign new deals — and Paul Pogba doesn't leave — then it gives the club a solid grounding of superstars.

“Other, younger players will then want to come."
