Adam Lallana can play a key part as Albion aim to upset Liverpool.

But the former Reds star is still a doubt for Saturday’s game at the Amex.

Lallana left the win at Aston Villa at half-time after reporting some groin tightness.

Head coach Graham Potter today reported Lallana still needed “a bit more time” before a decision could be taken on whether he will face the champions.

But he added it would be “a bit foolish” not to tap into Lallana’s knowledge of the club he served for six years before returning south this summer.

Potter said: “We talk a lot generally anyway so it's totally normal that you would chat about somewhere where he spent six years of his career.

“We’ve had a slight chat but he's a player and that's his responsibility.

“My responsibility, as a coach, is to try to pick the right team and to put an idea together that gives us a chance in the game.

“But it would be a bit foolish of me not to use Adam as a resource.”

Leandro Trossard, who missed matches either side of the last international break, has trained this week and is available.

Potter said Solly March had “a slight feeling” in his ankle but added: “Nothing too bad. I think he should be okay.”
