ARSENAL and Manchester United are on high alert with Marc Guehi set to reject Crystal Palace’s new contract offer.

The 23-year-old has shone for England at Euro 2024 and now has a host of top clubs chasing his services as the Eagles look likely to lose their biggest three stars this summer.

Palace had been hoping to keep hold of centre-half Guehi for at least one more season after already selling Michael Olise to Bayern Munich.

And fellow England Euro 2024 ace Eberechi Eze has a £60million release clause, which both Tottenham and Manchester City are willing to trigger.

Guehi, who started the first four games of the tournament for the Three Lions but was suspended for penalty shoot-out victory over Switzerland on Saturday, still has two years left on his deal.

But unless Palace can persuade him to sign a new one then they may be forced to cash in.

The Eagles want Guehi to sign a new contract which would include a release clause when he returns from the Euros.

But SunSport has now learned he has no intention of doing so.

He is understood to be keen to explore his options this summer amidst interest from Manchester United.

The Red Devils are particularly impressed with the ease with which he has adapted to playing as England’s left-sided centre-back in Germany despite being right footed.
