Wilfried Zaha has handed in a transfer request at Crystal Palace, Sky Sports News understands.

Arsenal and Everton have been interested in signing the Ivory Coast international winger this summer.

Everton have seen a £70m plus James McCarthy and Cenk Tosun bid for Zaha rejected and remain interested in the winger.

It is understood that for a deal to happen Palace would have to compromise on their £80m valuation.

Zaha is understood to be very disappointed and disillusioned about the situation, according to Sky sources.

Arsenal had been keen on signing Zaha before they signed his compatriot Nicolas Pepe from Lille for £72m.
