Mane picked up the problem on international duty with Senegal and was withdrawn late on in Sunday's (AEDT) 2-0 FIFA World Cup qualifying triumph over Cape Verde.

It will be Mane's second lengthy spell out of the season, after picking up a three-match ban for a dangerous challenge on Manchester City goalkeeper Ederson in September.

The 25-year-old – who has three goals in five Premier League games – has only been involved in one domestic match since returning from that suspension, and now looks set for an even longer absence.
