Liverpool have been handed an injury boost as Adam Lallana returned to training on Thursday. The midfielder has been sidelined since the last international break as he was withdrawn during England's 2-2 friendly draw against Spain.

The 28-year-old picked up a groin injury, which saw him miss the Reds' last three fixtures. The Merseyside club settled for a goalless draw against Southampton and a 2-0 win over Sunderland in the league, which was followed by a 2-0 win over Leeds United in the EFL Cup quarter-final clash.

Jurgen Klopp earlier admitted that Lallana would be out for "two to three games" and the England international has already missed Liverpool's last three fixtures. According to the Telegraph, the German manager remains hopeful of the midfielder's return to the squad to face AFC Bournemouth.

It is likely that Lallana will be introduced in the starting lineup when Klopp takes his men to Dean Court. His return will be crucial for Klopp, who is already without several first team players.

Philippe Coutinho suffered an ankle ligament damage in Liverpool's 2-0 win over Sunderland. The Brazilian international was stretchered off the field and the former Borussia Dortmund manager confirmed the playmaker will be out until New Year.

Daniel Sturridge last featured in the Reds' goalless draw against Southampton and missed the clash against the Black Cats due to a calf injury. The Telegraph claims the former Manchester City and Chelsea man will miss Liverpool's trip to Bournemouth as he is still recovering.

The England international was expected to fill in the void left by Coutinho's injury absence. However, failure from Sturridge to be fit for the Bournemouth fixture will force Klopp to look elsewhere.

Liverpool are already without the services of Danny Ings, who is out of action for the rest of the season after suffering a serious injury. Coutinho and Sturridge will join him in Liverpool's treatment room.

Roberto Firmino and Joel Matip missed their side's EFL Cup win over Leeds. According to Sky Sports, the duo will be fit to face Bournemouth as the attacker and the defender join Lallana to hand Klopp a triple injury boost.
