William Gallas reckons Hakim Ziyech could end up being Chelsea’s answer to Man City’s Riyad Mahrez.

The former France ace heaped praise on Frank Lampard’s Dutch star describing him as the best signing of the Blues’ summer transfer window.

Gallas told Ladbrokes: “I think he’s a great addition to the Chelsea squad and would probably say he was their signing of the summer.

“He’s a player who can make the difference. When he’s on the pitch you always fancy Chelsea to create chances and score goals.

“He’s a very clever player. He’s a little bit like Riyad Mahrez, and when you play against a team who are difficult to break down, someone like Ziyech is a great asset to have to make the difference.”
