Liverpool goalkeeper Alisson has been ruled out of the first leg of the Champions League last-16 tie against Galatasaray through injury - but he could be back for the visit of Tottenham at the weekend.

The 33-year-old Brazilian sustained the injury in a training session shortly before Liverpool flew to Turkey for Tuesday's match at RAMS Park.

Reds boss Arne Slot told a news conference on Monday that Alisson felt minor discomfort and after consultation with the club's medical staff did not travel to Istanbul with the rest of the squad. Liverpool have not disclosed specifics about the injury.

"Ali, of course, was in the session as many people could see, but unfortunately he felt something towards the end of the session," Slot said.

"People looked at it and we decided, and he decided together, that it wasn't good enough to play tomorrow. And then it's of no use travelling."

When asked if Alisson would be fit enough for Liverpool's Premier League fixture against Tottenham at Anfield on Sunday, Slot was positive.

"There's definitely a chance, yes, because we don't expect it to be a big thing," added the Dutchman.

"But it was too much to be available for tomorrow."

Brazil international Alisson has missed nine matches this season through injury.

His absence means Giorgi Mamardashvili is poised to make his first appearance for Liverpool since the FA Cup win over Barnsley on 12 January.

The Georgian has featured 11 times for Liverpool in all competitions this season.

Liverpool are also without Italian forward Federico Chiesa, who has not made the trip to Istanbul because of illness.
