Chelsea manager Thomas Tuchel admits Hakim Ziyech may be suffering in his system.

The Morocco international scored in the win over Atletico Madrid on Wednesday.

Tuchel was happy with his performance but admits his system might be stifling Ziyech's creativity.

Speaking after the 2-0 victory, Tuchel said: "He played today because he did it with Ajax and he came to a semi-final. He has good experience in the Round of 16, he knows how it feels to arrive in the knockout round and go through to the last eight.

"The second reason he played is because he deserved it and the third is we missed Mason Mount and we wanted to replace his work-rare and intensity with Hakim because we knew we faced a midfield of three with a lot of quality.

"Maybe he suffers a bit to adapt to our style because he loves to play creative and he needs to adapt to the structure but he gives a very reliable work-rate for the team."
