Liverpool manager Jurgen Klopp has confirmed Adam Lallana's injury and revealed the midfielder will be out of action for at least "two to three games". He limped off in England's 2-2 friendly draw against Spain at Wembley and failed to make it to the squad for the Reds' trip to Southampton.
The England international failed to be fit enough to face his former club at St Mary's Stadium on 19 November as the Merseyside club settled for a goalless draw. Following the match, the German boss admitted that Lallana's injury, which he picked up while on international duty is serious, which will force him to spend time on the sidelines.
"Adam Lallana is not in because he picked up an injury with England. It was serious enough to be not involved against Southampton and possibly the next two or three games. We don't know exactly in the moment but that was the only problem we had," Klopp explained, as quoted by the Liverpool Echo.
The Echo claims the former Southampton man has picked a groin injury while on international duty with England.
Klopp's side host Leeds United in the quarter-final of the EFL Cup clash at Anfield on 29 November. That fixture is sandwiched between two Premier League ties against Sunderland and AFC Bournemouth.
It should be seen whether Lallana can return to full fitness to start against Eddie Howe's side on 4 December. Should he miss the tie to face Bournemouth, he will be hoping to return to the squad when the Reds host West Ham United a week later.
The draw against Southampton saw Liverpool lose the top spot to Chelsea, who managed a narrow 1-0 win over Middlesbrough. Diego Costa's goal was the difference between the two sides in the end as Antonio Conte's side walked away from the Riverside Stadium with three points.
Liverpool are second in the table with 27 points after 12 games, level on points with third place Manchester City. These two sides are trailing leaders Chelsea by a point.
