Chelsea manager Thomas Tuchel has said Hakim Ziyech is still adapting to English football.

The Morocco playmaker has showed glimpses of his talent since arriving from Ajax in the summer.

And Tuchel confirmed he will start Ziyech in Thursday's FA Cup fifth-round clash with Championship outfit Barnsley.

"Hopefully tomorrow we see the best of him," Tuchel said ahead of his side's trip to Oakwell. "He had a good training week and we count on Hakim like on everybody else, there's absolutely no doubt about that.

"We took some decisions for other players, not against him but for other players, and he will have the chance to show tomorrow the same quality he shows in training, the same determination.

"For me, it's clear he needs to adapt to this kind of football, this kind of league. He comes from the Dutch league, from a strong Ajax squad but they were the benchmark in the league and it's not the same intensity and competition as it is here, but he is adapting.

"He has the certain quality to decide matches and the certain quality to do the unexpected which can give you an extra twist in any game and on a level which he proved with Ajax. Of course, we want to push him to the same level of performance that he showed there and this is our job."
