Thomas Tuchel has revealed his relief at Tammy Abraham avoiding a lasting ankle injury but confirmed that Thiago Silva will miss Chelsea's trip to face Southampton on Saturday.

England striker Abraham should be fit for the Premier League fixture, having made a quick recovery after Monday's ankle issue.

Chelsea boss Tuchel criticised Jamaal Lascelles' "reckless" challenge on Abraham in Monday's 2-0 win over Newcastle, revealing his "worry" that the Blues striker could have picked up a serious problem.

But now Abraham is expected to be ready for the weekend, with Tuchel delighted to have the 23-year-old fit so quickly.

"We're very happy that Tammy is very, very good," the Blues boss said.

"He feels very good, he's free for training today at three o'clock. And if things go well he's in the squad (for Southampton)."

But Brazil defender Silva will miss Saturday's lunchtime kick-off clash despite being back in training as he continues his recovery from a thigh issue.

Christian Pulisic and Thomas Tuchel 

Tuchel has insisted Chelsea want to keep hold of Christian Pulisic and help the United States international reach his full potential at Stamford Bridge.

Pulisic was withdrawn from Chelsea training on Thursday with a twinge to his calf, in the latest in a string of muscle problems.

Blues boss Tuchel says Pulisic has not suffered any severe new injury, but conceded that Chelsea's medical staff are working hard to move the 22-year-old past his spate of issues.

Pulisic has been linked with a move away from west London in the summer, but Tuchel is determined to see the talented forward shine with the Blues.

Asked if he wants Pulisic to stay at Chelsea, Tuchel replied: "Today a clear 'yes', but it's not only my point of view, we have to see. But for me clearly yes.

"Chelsea bought Christian for a reason, for his quality, his potential and it's our job to bring out the best in him.

"He proved in many weeks that he has the level to be a regular Chelsea player, to have a big impact in this club. It's a challenge now to hold this level, to improve and to maintain the level and to keep improving.

"We are not concerned, we are not worried, but the medical department is on that. Now we have little issues in the calf, he stopped training yesterday before it became an injury."
