Cenk Tosun is finding playing in the Premier League difficult, according to manager Sam Allardyce.

The striker was a £26 million signing from Turkish club Besiktas in January.

Allardyce said: "He is struggling with the pace of the Premier League which happens to more players than it doesn't who come in January.

"There are more that struggle than actually succeed. As time goes on and the more we get closer to our safety the more we can release and see what he's got".
