Alisson Becker will be sidelined for ‘the next few weeks’ due to the calf injury he sustained during Friday’s win over Norwich City, Jürgen Klopp has confirmed.

The goalkeeper was forced off in the late stages of the first half as Liverpool got their Premier League season under way with a 4-1 victory at Anfield.

And Klopp expects to be without the Brazil international for a period of weeks.

“[It’s] Not too cool. It’s a calf injury which takes him obviously out for a while,” the boss told Liverpoolfc.com.

“I don’t want to make now [an] exact prognosis on when he will be back but it will not be Wednesday for sure, so then we have to see. It takes a while, it takes a couple of weeks for sure, and we have to see.

“I saw already like ‘six weeks’ and stuff like this, but Ali was not a lot injured in his career so I would like to wait a little bit to see how he develops in that process now. But he is not in for the next few weeks.”
