The Blues manager was hugely impressed by the former Ajax playmaker’s contribution in his side’s 4-1 win over Sheffield United, where he provided two assists.
Goals from Tammy Abraham, Ben Chilwell, Thiago Silva and Timo Werner sealed the points for Lampard’s men, but it was Ziyech’s performance that caught the eye.
Discussing the man of the match after the contest, Lampard hailed the ‘different element’ he brings to his new-look Chelsea side.
But he was keen to stress that it’s the completeness of Ziyech that made him such an attractive proposition when he became available for transfer.
‘He’s given us an extra edge and a different threat,’ said Lampard. ‘He’s been out of football for a long time so I think it’s really impressive how he’s hit the ground running.
‘He gives us a different style in terms of the left foot off the right side. It’s not something we’ve had much of in recent years.
‘The ability to find the last pass or the last cross, to break teams down with a low block. We saw that today, we clearly saw that today.
‘His personality has rubbed off. I keep talking about personality – it’s a huge thing in football. The signings that we’ve brought in, a lot of them are bringing a lot on and off the pitch. That’s important.
Lampard added: ‘He’s brought a different element to our game, he sees the pass and has no fear to try the pass even if he’s missed the last pass because he’s trying to play game-changing passes regularly.
‘There’s a lot of parts to his game. I wouldn’t want to just lean on that. I think his work ethic off the ball as well, his work for the team means he’s a very complete player.
‘I expect a lot more to come from him.’
