But, as of Friday morning, Jürgen Klopp said there were no other issues for the Reds, who are aiming for a response to their defeat against Manchester United last weekend.

Adam Lallana was one of four Liverpool players included in Gareth Southgate’s England squad this week, prompting a question on the No.20’s current condition at the manager’s pre-match press conference.

“For us it’s a big challenge to have him around and not to bring him [on the pitch], to be honest, because maybe in the moment he needs a little bit longer,” he said.

“It’s not because of age or whatever, from all other points of view he’s in fantastic shape, but he needs a little bit more recovery time, stuff like that, and we needed all to learn and deal with that.”

Trent Alexander-Arnold started each of the past five Premier League matches but has Joe Gomez snapping at his heels for an opportunity at right-back.

Klopp commented: “Joe had a little injury only but that can sometimes mean you are out for two or three games because the other one is playing pretty well. That is what happened.

“Now we will see who will start at the weekend.”

Watford have centre-back Craig Cathcart available after injury and goalkeeper Heurelho Gomes, who missed last weekend’s 3-0 defeat at Arsenal, comes into contention again.

“Craig is now fully training,” said head coach Javi Gracia. “He wasn’t an option because he wasn’t in the best condition, but he is improving day by day in training with the team. He is now an option.”

The Spaniard remains without a significant number of first-team players, however.Nathaniel Chalobah, Tom Cleverley, Christian Kabasele, Gerard Deulofeu,Younes Kaboul and Molla Wague are unavailable.

“This week nobody new was training with the team,” explained the Hornets boss. “We need to wait more time for injured players. The rest are in a process of recovery.”
