Thomas Tuchel has revealed his worry over Tammy Abraham’s nagging ankle injury after the Chelsea forward suffered a new setback in training.

Abraham has battled the issue since hobbling out of Chelsea’s 2-0 win over Newcastle at Stamford Bridge on February 15.

The 23-year-old has made five appearances since that initial problem, but failed to complete Chelsea training on Thursday and will now miss Saturday’s Premier League trip to Leeds.

“First of all it’s most important he feels safe, free and zero pain, and then we can think about his comeback.”

Brazil defender Thiago Silva has suffered a minor recurrence of his prior thigh problem, so will also miss Saturday’s Elland Road clash.

Tuchel added: “Thiago also had a little setback in training, at the end of the training session, the day before yesterday. He felt at the very end, something around the same area where he was injured.

“So we had to take him off and he’s back into a transition phase but not back in team training. So he will be out.”
