Frank Lampard praised Hakim Ziyech's start to his Chelsea career as "remarkable" after the forward's starring role in the 4-1 win over Sheffield United.

The Blues recovered after conceding for the first time in 459 minutes in all competitions through David McGoldrick's ninth-minute effort to keep pace at the top of the Premier League table.

Goals from Tammy Abraham, Ben Chilwell, Thiago Silva and Timo Werner ensured a victory that puts Chelsea a point behind leaders Southampton and second-placed Liverpool.

Ziyech had a hand in three of the goals at Stamford Bridge, supplying two assists, and creating a game-high six chances.

The former Ajax man created the most chances of any player in the league this season, and Lampard is particularly impressed with how he has adapted given the 2019-20 Eredivisie season was abandoned back in April.

"We played against [Ziyech] in the Champions League last year - he's a top-class player," Lampard told Sky Sports. "He impresses you even more when you work with him.

"The Dutch league finished a long time ago, then he had an injury so to hit the ground running like he has, he has been remarkable.

"He will be a big player for us. I need players who can come in and lift the level. That's hard. The midfield were great with their driving runs."

Chelsea boss Lampard was impressed with his side's response to going behind, adding: "Sheffield United are a really strong team.

"They are really good at putting you under pressure. We didn't deal with it brilliantly but the reaction from the team for the rest of the game was spot on."
