Bolasie leaves Palace for Everton

Congo forward Yannick Bolasie has joined Everton from Premier League rivals Crystal Palace on a five-year contract.

Financial terms were undisclosed but media reports on Monday said Everton had paid an initial fee of STG25 million ($A42.20 million) for the 27-year-old.

Bolasie, who joined Palace from Bristol City in 2012, follows recent new recruits Ashley Williams, Idrissa Gueye, Maarten Stekelenburg and Shani Tarashaj to Everton.

"It was a no-brainer to come here but now I've come to Everton, the job is not done. I've got to work hard and feel my way in. I'm ready and up for the challenge," he said in a statement.

Bolasie has been capped 27 times by his country, scoring seven goals. He netted nine goals in 90 Premier League appearances for Palace.

Everton's new manager Ronald Koeman said the player would add speed, strength and versatility to his attack.
