Liverpool boss Jurgen Klopp has issued an upbeat update on the recovery of goalkeeper Alisson.
The Brazilian international has been sidelined since the Red's Premier League opener win over Norwich, in which he picked up a calf injury.
"Alisson is making big progress. A proper session yesterday with goalkeeping coach John Achterberg," Klopp said when asked about Alisson's progress.
"Not in team training yet, and we take it day by day. We will see. Too early to say. The medical department will tell me."
The Liverpool manager also revealed that midfielder Naby Keita and striker Divock Origi are unlikely to feature in Sunday's match against Chelsea at Stamford Bridge.
“Naby Keita is back in training at least, with the team. Today for the first time with the team.
“Div, we have to see day by day, that’s how it was from the first day – how can he deal with the pain and stuff like that. We will see. It is pretty early, so I don’t know exactly what the medical department will tell me about that case.
“I think it’s unlikely he will be fit for Chelsea but why should I rule him out? But it’s unlikely.”
Klopp also feels his team could cope with an injury to their UEFA Player of the Year Virgil van Dijk.
"That is the reason why we have four centre-halves.
"It is not easy for the in-the-moment number four not playing but if something happens, like last year a couple of things happened and then you end up with one centre-half and a defensive midfielder like against Bayern at home with Fabinho and Joel Matip as centre-halves.
"That can happen, it was unlucky, but you cannot think about injuries before you have an injury. We all need luck to be really successful."
