LIVERPOOL, England (Reuters) -Liverpool will be without first-choice goalkeeper Alisson Becker when they host arch-rivals Manchester United in the Premier League on Sunday, adding to the pressure on manager Arne Slot as his side looks to snap a three-game losing streak.

"He will not play and also not next week," Slot told reporters on Friday. "Alisson, he is not training. It's so difficult to say (when he will return) because the end phase of rehab can give positives and negatives."
