Chelsea hero Gus Poyet was bemused by the timing of Hakim Ziyech's signing.

The Blues didn't sign a single player in January, but agreed a deal the following month for Ajax star Ziyech, who will join the club this summer.

Poyet said: "I didn't understand – and I'm not criticising anyone – why Chelsea, after all that went on in the summer, not being able to sign players, get to January with the possibility of signing players, they didn't, and then three days later, four days later, they announce they sign a player for next year. It's not normal, okay?

"I'm not saying it's bad, but I lost it a little bit because you complain a lot about not being able to buy, then you have the chance to buy and you don't, and then when the transfer window is closed you announce that you bought one.

"Leaving that aside, I think they got the quality of a player the fans will enjoy watching.

"Obviously, there's going to be a period of adaptation, and it all depends on where you came from, your character, and how they can perform, but if he adapts himself to the strength and power of the Premier League, I think he's going to be a player you're going to go and enjoy watching play.

"Plenty of skill, technically gifted, can score goals, and he can produce things for the team."
