Liverpool's squad depth fills Adam Lallana full of hope for the coming Premier League campaign.

The attacking midfielder's battle for a starting spot in Jürgen Klopp's side will be as tough as ever, with the arrivals of Georginio Wijnaldum and Sadio Mane adding to the Reds' attack.

With Philippe Coutinho and Roberto Firmino among those competing for places behind the striker, Lallana insists Klopp's abundance of options can only be a good thing.

Liverpool kickstart their season away at Arsenal on Sunday and Lallana believes the selection headaches that face Klopp will help the squad as a whole.

He insisted that they have "loads of different players" who "can play loads of different positions" at the club after their summer business.

The England international explained that Klopp "has got decisions to make" but said that such "competition for places" is "great for the squad."

Lallana is also confident that Mane - a £30 million arrival from Southampton this summer - can have a telling impact on the Reds' success across 2016-17.

The Reds' No.20, who also joined from the South Coast club two years ago, is pleased with the qualities that Mane adds to the mix.

"Sadio can go down the outside, he can come inside, he has got a goal in his locker like he produced against Barcelona," continued Lallana, who declared: "He's a very good addition the squad, believe me."

The 28-year-old insisted that it took just a few training sessions to see his talent, saying that "straight away" he could see what Senegal international Mane "was about" and "what he was going to bring to the team."

Lallana believes his new teammate showed as such with his performance in their 4-0 victory over Barcelona, insisting that "all those different parts" against the Catalan giants could be seen "in his first couple of sessions" at their training ground.

"We have seen it from working with him, what he can do," continued Lallana, who said that he was "never worried" about Mane "settling" in on Merseyside and on his performances in pre-season said that he "could have had a goal against AC Milan."

He declared that he "could see what he was going to bring to this team" early on because he's "different" to the other options Klopp has in the squad and is "unpredictable."
