Everton are interested in signing Crystal Palace winger Wilfried Zaha this summer.

Marco Silva has been a long-time admirer of the Ivory Coast international and is keen to make him his first signing at the club.

Everton will however have to stave off competition for Zaha, with Borussia Dortmund and Tottenham both understood to hold an interest in the player.

Spurs have been chasing Zaha for a considerable amount of time and are still monitoring his situation despite last week being told they will have to bid in the region of £70million to sign him.

The north London club are looking at alternative options but may test Palace's resolve with a lower offer after Everton joined the race for the winger.

Palace's £70m valuation may also price Everton out, but the club are willing to explore the possibility of selling Yannick Bolaise in order to raise money to fund the move.

Bolasie is currently in Austria with the rest of the Everton squad for their week-long training camp but is being heavily linked with a move to Turkish side Fenerbache.

Everton are also yet to clarify the future of Ademola Lookman, who is being courted by RB Leipzig after impressing during his loan spell at the club last season.

The English forward is understood to be keen on a return to Germany but could be tempted to stay should he receive assurances over more first-team action next season.

Leipzig manager Ralf Rangnick claimed on Monday that Lookman's preference is to re-join them and that the two clubs are currently in the process of negotiating a deal.

Lookman's club-mate Henry Onyekuru departed Goodison Park this week to join Galatasaray on a season-long loan deal.
