Liverpool are reportedly sweating on the fitness of Adam Lallana 11 days before the team's showdown against Manchester United at Old Trafford.
The 28-year-old was forced to withdraw from England's World Cup qualifiers against Malta and Slovenia due to a groin injury that he suffered at the weekend.
The midfielder was substituted in the 23rd minute of Liverpool's 2-1 victory over Swansea City at the Liberty Stadium.
According to the Liverpool Echo, Lallana has not been ruled out of the Premier League clash against his club's arch rivals, but the Reds are yet to make a final decision as they continue to monitor the player closely.
Meanwhile, it is believed that Nathaniel Clyne and Dejan Lovren will be fit for the match.
