Manchester United may need to bid up to £60million to land Aaron Wan-Bissaka this summer after having an offer worth over £40m rejected by Crystal Palace.

Right-back Wan-Bissaka is one of United’s principle transfer targets and the club made their first move for him earlier this month, which Palace swiftly turned down.

But sources believe a bid worth around £60m may force Palace to consider selling the 21-year-old, even though they are desperate to keep hold of him.

Wan-Bissaka is currently with Aidy Boothroyd’s England Under-21 squad preparing for the European Championships in Italy and San Marino.

He is contracted to Palace until 2022, which means the Eagles are under no pressure to sell one of their prized assets.

Wilfried Zaha has already expressed a desire to leave Selhurst Park this summer, but Palace value the forward at a minimum of £80m.
