Asked for an update on Firmino’s condition and specifically whether he may play against Boro at Anfield next Sunday, the manager said: “Not a real idea, but it’s a bigger chance than for this game today. We tried a little bit on Friday, only with a little running. [But] he still felt the muscle, so [there was] no chance.

“He struggled a little bit in the last few weeks with different parts of his body. We always had to manage the intensity with him, did it and then in the game he actually didn’t really feel it. Then after the [Southampton] game, he said ‘Yes, now I feel something’ and that was too much for training last week.

“But [he has] another week and being an option would be cool for us.”

Firmino has been a nailed-on starter for Liverpool this season, making the team in 33 of their 37 Premier League appearances.

The Brazilian has responded with 11 league goals that have been supplemented by nine assists in the competition.
