Lallana started in both of the Three Lions’ clashes in March, and laid on Jamie Vardy’s goal in Sunday’s 2-0 win at home to Lithuania.
But on returning to Merseyside to rejoin Jurgen Klopp‘s squad in preparation for Saturday’s Merseyside derby, scans have revealed a big blow to the Reds’ top-four hopes.
The 28-year-old is expected to be sidelined for the next month, keeping him out of a key period of the season.
While it is hoped Lallana will return ahead of schedule, the midfielder will undoubtedly miss a clutch of Liverpool‘s crucial games as they look to end the season on a high.
Lallana will definitely be absent for Saturday’s Merseyside derby, and he could miss a further four games if he is out for a month.
Lallana has reached a new plateau under Klopp in 2016/17, scoring seven and assisting seven in 27 games in the Premier League so far, excelling in a new role in central midfield.
His ability both on and off the ball have provided Liverpool with an invaluable outlet, with Lallana leading Klopp’s high-intensity pressing game.
Jordan Henderson is currently stepping up his recovery from a troubling foot injury, and is still a doubt for the derby.
If Klopp is without Henderson, Lallana, Coutinho and Firmino from the start at the weekend, Liverpool could be a much-changed side.
