Liverpool forward Roberto Firmino is a doubt for Wednesday's Champions League semi-final first leg in Barcelona .
The Brazil international missed the 5-0 victory over Huddersfield with a minor muscle tear and manager Jurgen Klopp admits he does not know whether he will recover in time.
"Bobby trained yesterday completely normal. It was not high intensity, we had to work on set-pieces a bit, a couple of things," said the Reds boss.
"I didn't see it in training, it happened obviously in the last situation in training, he felt the muscle a little bit.
"Now that's the official diagnosis: 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 in the moment.
"Because it's him it's more likely than not, but we will see.
"Of all the badness you can get it's pretty much the best, but it's still bad enough that he couldn't play tonight."
The most fouled team in the Premier League this season revealed
That victory took Liverpool back to the top of the table and restored their two-point advantage over City, who face a potentially tricky trip to Turf Moor.
It lifted the Reds to 91 points and it is remarkable to think they could finish the season with 97 points, the Premier League's two leading goalscorers - Mohamed Salah took his tally to 21 and Sadio Mane 20 as both scored twice against the Terriers - and potentially the PFA Player of the Year in Virgil Van Dijk and still not win the title.
