Liverpool striker Roberto Firmino is battling to be fit for their Champions League semifinal first-leg clash with Barcelona.

Firmino missed Friday night's 5-0 Premier League romp against Huddersfield Town at Anfield that moved the Reds back to the Premier League summit.

The Brazilian has suffered a small tear of a muscle and will undergo intensive treatment ahead of Wednesday's first leg showdown at Camp Nou.

“Bobby trained yesterday (Thursday) completely normal," said Reds boss Jurgen Klopp. “It was not high intensity. We had to work on set-pieces a little bit and a couple of things.

“I didn't see it in training, it happened after the last situation in training he felt a muscle a little bit.

“The official diagnosis is that he has a small tear in a very small muscle. Apart from the word 'tear' everything is positive.

“It's Bobby, so he might be ready for Wednesday but we don't know obviously at the moment.

“But because it's him, it's rather likely than not. But we will see.

“Of all the bad news we could get, it's probably the best. But it's still bad enough that he couldn't play tonight."
