Adam Lallana has made 21 appearances for Liverpool this season, scoring four goals

Liverpool midfielder Adam Lallana is facing up to a month on the sidelines with a damaged calf muscle.

Lallana, who scored a brace in last month's 4-1 win over Swansea, started a sixth successive match against Leicester City on New Year's Day but was forced off after 55 minutes.

The 26-year-old is out of Monday's FA Cup third-round tie at AFC Wimbledon.

He also misses both legs of the League Cup semi-final with Chelsea and league games with Sunderland and Aston Villa.
