Chelsea hero Frank Leboeuf says manager Thomas Tuchel isn't playing Hakim Ziyech to his strengths.

Ziyech arrived at Stamford Bridge for £33million last summer, but has only started 14 Premier League games for the Blues.

Leboeuf told ESPN: "I'm concerned about Hakim Ziyech. If he plays, why doesn't he [Tuchel] put him on the right?

"I saw him today very frustrated when he came off after playing like a number 10. I don't think that's his real position.

"Tuchel really has to think that Ziyech has to play on the right side. It's like [Riyad] Mahrez, he's a copy-cat of Mahrez.

"I don't see [Pep] Guardiola putting Mahrez in another position than on the right side."
