Liverpool have been handed a major injury boost for the Merseyside derby against Everton after star midfielder Adam Lallana returned to training on Friday (8 December).

The England international has featured once this season as a substitute appearance against Chelsea – having spent time on the sidelines before the start of the season due to a hamstring injury.

Lallana suffered a minor muscle strain, which kept him out of action for Liverpool's last three matches. The Reds manager Jurgen Klopp confirmed the former Southampton man's injury is "nothing really serious" in November.

"And Adam, it's a minor muscle thing, nothing really serious but he needs a few days to recover from that and then he's back in training and then in the squad," Klopp explained.

The 29-year-old has now returned to training and was spotted at Melwood, the club's training ground. It should be seen whether Lallana will be fit to face for Sam Allardyce's men's visit to Anfield on 10 December.

According to Liverpool's official website, Lallana "could be in line to return" to face Everton during the derby clash on Sunday. Jurgen Klopp will have a decision to make whether to start the midfielder against the Toffees.

Mohamed Salah, Sadio Mane, Roberto Firmino and Philippe Coutinho, who are dubbed as the "Fab Four," impressed in their 7-0 win over Spartak Moscow in the Champions League. This helped Liverpool to seal a berth in the Champions League knockout stages and also finish on top of their group.

The former Borussia Dortmund manager refused to confirm if the newly dubbed "Fab Four" would start against Everton.

"I have nothing to say about the line-up from our side. Actually, I didn't decide it so far. We played on Wednesday and we have to wait for sure today and maybe until tomorrow to make a line-up," Liverpool manager explained.

One player who will miss Everton's trip to Anfield will be defender Alberto Moreno. The former Sevilla player was forced off in their last European fixture against the Russian outfit. Klopp confirmed there is a "little damage" around the full-back's tendons, but refuse to provide an update on how long the player will be on the sidelines.

"We need to have further assessment. I cannot say much about it. It's a very rare thing. So far the specialists aren't sure [how long he'll be out for]. Not Everton, but if it's in a week or so or a little bit longer we have to wait for that. There's a little damage around the tendons," Klopp said.
