Manchester United are ready to battle Paris St-Germain for Jadon Sancho in a tug-of-war that could see the Borussia Dortmund winger become the first £100 million English footballer.

Sancho has emerged as the top summer forward target for both United and PSG, who face each other in the second leg of their Champions League Round of 16 tie at the Parc des Princes on Wednesday night.

Any move for the teenage England winger would raise fresh doubts over the future of Alexis Sanchez, who has been a spectacular flop since his move to Old Trafford from Arsenal 14 months ago.

Sanchez’s calamitous United career hit a new low on Monday when he was ruled out for up to two months with medial ligament damage to his right knee as Ole Gunnar Solskjaer’s injury crisis deepened ahead of the PSG game, in which United must try to overturn a 2-0 first-leg deficit.

But, despite Sanchez’s injury leading some to wonder if the Chile forward might have played his last game for United, his exorbitant £500,000-a-week wages will make him difficult for the club to offload unless a move away is subsidised or there are huge compromises on both sides.
