Liverpool goalkeeper Alisson Becker will be out until after the next international break in mid-October but midfielder Naby Keita should return to training with the first team next week, manager Juergen Klopp said on Friday.
Brazilian Alisson injured his calf in Liverpool's Premier League opener against Norwich City last month and the European champions have kept only one clean sheet in all competitions in his absence so far.
Keita, who suffered a groin injury last month, has missed Liverpool's last three matches.
"Alisson looks good and he is improving, but we cannot put any pressure on it," Klopp told reporters ahead of Saturday's home game against Newcastle United. "It was a really serious injury in the calf.
"It is now much better and that's good for us and good for him, but we don't know exactly (how long it will take). The target was always after the next international break.
