Despite managing to keep their winning run in the Champions League going with a 2-0 win over Atletico Madrid in midweek thanks to goals from Diogo Jota and Sadio Mane, it wasn't a perfect night for Liverpool in one regard in particular.

What's the news?

After replacing Mane at half time, Reds attacker Roberto Firmino went off with an injury in the 78th minute and was replaced by Divock Origi.

In a tweet from Liverpool journalist James Pearce, Reds manager Jurgen Klopp reportedly revealed that the Brazilian had suffered a hamstring injury that forced him off the pitch in the second half.

The reporter wrote the following seven-word update: "Klopp says Firmino has a hamstring injury."

Big blow

So far this season, Firmino has made 11 appearances for the Reds across all competitions in which he has managed to score six goals and provide one assist in the process, which makes this a huge blow for the Reds if he's going to be out of action for a significant period of time.

Liverpool also have Naby Keita and James Milner out with hamstring injuries so it's safe to say that this latest update via Pearce will have a lot of Liverpool fans gutted, especially considering they have a big Premier League match against West Ham United to prepare for.

The Irons are only two points behind the Reds in the league table so having Firmino available would have been a sizeable advantage for the Merseyside outfit.

Since joining the Reds in a deal worth a reported fee of £29m, the 30-year-old, who is currently valued at £36m according to Transfermarkt, has made a total of 303 appearances for the Reds across all competitions. In that time he's beaten the goalkeeper on 93 occasions, supplying 70 assists and proving himself as an important figure for the team.

While it's a shame that Firmino has picked up this injury, at least Liverpool have Jota, who has five goals and two assists under his belt so far this season, to potentially fill in for the Brazilian for the time being.

That said, with the Reds progressing in the Champions League and Carabao Cup, whilst remaining in a close title race at the top of the Premier League table, Klopp and everyone else at the club will undoubtedly be hoping that Firmino gets back to full fitness as soon as possible.
