Everton have made a final offer to sign Besiktas striker Cenk Tosun.

The Turkey forward, 26, has been a top transfer target for Crystal Palace since the summer.

But a move to Goodison Park looks increasingly likely this month – with the Toffees set to make a final £25m bid.

Speaking about their lack of goals, Everton boss Sam Allardyce said: "Our ratio of chances created is very limited.

"That is because we need to strengthen that frontline. I think we all know that.

"We are trying to do the hardest job of all by securing a player in that position.

"It was not achieved before the start of the season and it may not yet be achieved this January.

"Obviously we need a bigger goalscoring threat than we have got at the moment. That may help us in many ways to achieve more results.

"It certainly will if whoever we get scores goals. But I can't guarantee whoever we get in is going to score goals straight away.

"I just hope he does [score] when we do."

Tosun has scored 41 goals in 96 league appearances since joining Besiktas in 2014.
