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.
