Former Holland striker Youri Mulder says Hakim Ziyech has already established himself as Chelsea's best player.
Ziyech struck in victory at Burnley on Saturday.
And Mulder said on Ziggo Sport: "It's not at all hosanna what Chelsea does, but Ziyech is Chelsea's best man, I think.
"It's slow and lumbered at Chelsea, there are no automatisms. You don't see often that someone is being played in, and the third man in a move already starts walking.
"Ziyech is withdrawing from that. He thinks: what kind of mess is that? I can do that better..."
