London: Liverpool goalkeeper Alisson Becker has been ruled out for “the next few weeks” by boss Jurgen Klopp after suffering a calf injury in the 4-1 win over Norwich. Alisson limped off in the first half of Liverpool’s Premier League opener at Anfield on Friday. Klopp revealed on Monday that he does not expect the 26-year-old Brazil international to be available for several weeks. “Not too cool. It’s a calf injury which takes him obviously out for a while,” Klopp told Liverpool’s website.

It takes a while, it takes a couple 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.” Alisson was replaced by experienced Spaniard Adrian against Norwich. The former West Ham keeper, who joined on a free transfer last week, is likely to keep his place for Liverpool’s European Super Cup date with Chelsea in Istanbul on Wednesday. Third-choice Liverpool keeper Caoimhin Kelleher is not fully fit after a broken wrist, so the club are reportedly considering signing 35-year-old former Middlesbrough player Andy Lonergan on a free transfer.
