The goalkeeper has been out of action since sustaining the problem during the first half of the Reds’ opening weekend win over Norwich City at Anfield.
The Brazil international has been working hard on his fitness levels at Liverpool FC’s Melwood training base in recent weeks but he is still not quite ready for a comeback.
However, Klopp seemed to be happy with the progress that the shot-stopper is making in his recovery judging by the comments he made before the clash with Newcastle United this weekend.
Speaking during his pre-match news conference, Klopp said: “Funnily enough, we had lunch together [just now]; he looks good and he is improving, but we cannot put any pressure on it.
“It was a really serious injury in the calf. It is now much better, of course, and that’s good for us and good for him, but we don’t know exactly [how long it will be].
“The target was always after the next international break [that] he could be ready, but we don’t know. So, as I said, there is no pressure and hopefully everything will be fine for the rest of the season, that’s the plan.”
Klopp also delivered an update on midfielder Naby Kieta, who is currently sidelined with a hip injury.
He added: “Naby is close, much closer than Ali. I think he could be in training when we come back from Napoli next week.”
Liverpool FC will kick off the defence of their Champions League crown on Tuesday night when they travel to Napoli for their group stage opener.
