He is likely to make his Seagulls debut against Chelsea on Monday evening and head coach Potter believes the player will make a major impact at the club.

"I can speak a lot about what you need to do and I can give advice but you've got somebody in our environment that has seen it first-hand and has achieved it," said Potter.

"And that's very powerful from a leadership perspective, from a culture perspective, from how we work every day and how we have to act on the pitch, and how we have to act on the training ground.

"There are some little things that can be improved on there and I think Adam brings that.

"He's a fantastic person, a really good character, good team-mate, wants to help the players. He's not just focused on himself, he cares about the team, he cares about the players around him. That's something that is important for us.

"And he also brings a quality on the football pitch. We are pleased with him and pleased that we have him here. We have to make the most of that and help him enjoy his football.

"I can understand why he was a young captain (at Southampton), I can understand why he was so respected at Liverpool. From the short time we've seen him and worked with him, he's been fantastic for us."

While Lallana adds inventiveness to Brighton's midfield, the club have not yet added to their striking options.

Albion struggled to find the net on a consistent basis last season and did not guarantee top-flight survival until a goalless draw at home to Newcastle in their penultimate fixture.

Potter, who has allowed veteran striker Glenn Murray to join Watford on loan, has not ruled out adding to his attacking options but is eager to elicit more from the forwards currently at his disposal.

"The likes of Neal Maupay, Aaron Connolly, Leo Trossard, Alireza (Jahanbakhsh), if you look at their goals last year, you think they can improve those tallies," said Potter.

"And rather than look for the silver bullet that's out there, we sort of think, 'can we improve those guys? Can we help them score more?' because three of those four were making their first starts in the Premier League.

"You'd like to think they can take a step forward and that might mean the goals can come from within.

"You're always looking to see if there's somebody that can bring something extra and help the guys already here, so we'll keep working in that regard but the most important thing is to help the guys we've got take the next step."
