More hamstring problems for Chelsea star Pulisic

Christian Pulisic could be facing more time on the sidelines after suffering a hamstring injury during the warm-up for Chelsea’s 3-0 win over Burnley on Saturday.

The American midfielder was named in the starting line-up by Frank Lampard at Turf Moor but the Chelsea boss was forced into making a very late change to his team when he complained of pain the same hamstring he injured in the FA Cup final that kept him out for almost two months.

“He had a small sensation in his hamstring so we had to pull him from the game after the warm-up,” Lampard said.

“He’s frustrated, he’s just got fit. I rested him in the week and he came on and scored.

“We will have to scan it and see how it is. I don’t have any more information than that.”

Chelsea were ruthlessly efficient in front of goal with the impressive Hakim Ziyech scoring his maiden Premier League strike in his first start along with efforts from Kurt Zouma and Timo Werner, who replaced Pulisic.

The Blues were also much more solid in defence as they chalked up a fourth successive clean sheet with recently-signed goalkeeper Edouard Mendy yet to concede in his five appearances in all competitions since joining from Rennes.

“There was balance there today, but I don’t want to jump ahead and say that our balance is now done, we have to keep working on that,” Lampard said.

“But when you are keeping clean sheets and scoring goals you are going in the right direction.

“I really enjoyed that performance today. Some of the angles we were making, receiving the ball through the lines we were much more positive and aggressive in our forward passing.

“It was a nice step forward.”

In addition to the solidity at centre-half from Zouma and Thiago Silva, Lampard said the performances of full-backs Reece James and Ben Chilwell were crucial to securing victory over the winless Clarets.

“It’s an important part of how I want to play using the full-backs,” he said.

“I thought Chilly and Reece chose their moments well to join in in high areas of the pitch and then perfectly recover to their positions to challenge for the second balls.”
