Everton are closing in on three Premier League stars for a combined £60million after agreeing a fee with Crystal Palace for the transfer of Yannick Bolasie, according to a report.

Sky Sports claimed on their Twitter account on Tuesday evening that the Merseysiders had settled a stunning £30million deal for winger Bolasie.

The Toffees had previously made contact with Palace over the transfer of the Congo international and have come back with a £30million offer, which has been accepted by the Londoners.

The Bolasie fee is set to break Everton’s transfer record, which is the £28million they spent to prise Romelu Lukaku from Chelsea in the summer of 2014.

Everton could spend a sensational £60million on new players in a whirlwind period as they also close in on centre-back pair Ashley Williams and Lamine Kone.

Sky Sports claimed on their transfer centre blog (12:08pm) that Swansea skipper Williams would travel to Merseyside on Tuesday afternoon to undergo a medical ahead of signing a two-year deal.

Sky Sports also reported on their website that Sunderland’s Kone is on Merseyside on Tuesday with negotiations continuing over a move to Everton.

It is said by the broadcaster that Everton submitted an £18million bid for Kone more than a week ago and that they have agreed a £12million deal with Swansea for Williams.

New Toffees boss Ronald Koeman is keen to add more players to his side ahead of the new season and believes Bolasie, who graduated through the Rushden and Diamonds academy, is the perfect fit for his side.

The winger joined Palace from Bristol City in the summer of 2012 and has made 143 appearances for the Premier League club, scoring 13 goals and supplying 30 assists during his spell at the Premier League club.

Everton have hopes of a much more convincing season under Koeman, after a disappointing last campaign, which saw them finish 11th with one of the worst home records at Goodison Park in living memory.
