Forward Sadio Mane has become Liverpool's third most expensive signing after the club confirmed he had completed his move from Southampton.

It is understood the Senegal international has signed a five-year contract after a £30million deal was finalised.

That puts the 24-year-old behind only Andy Carroll (£35m) and Christian Benteke (£32.5m) in terms of the club's record signings.

The Senegal international, who scored 25 goals in 75 appearances for the Saints, is the fourth signing by manager Jurgen Klopp, who has already brought in centre-back Joel Matip, midfielder Marko Grujic and goalkeeper Loris Karius.

Mane will wear the number 19 shirt.

There has been some dispute between the clubs over Mane's fee with Southampton saying privately it is £34m rising to £36m with add-ons but sources at Anfield have rejected those claims.

Mane admits he did not have to think twice when Klopp asked him to join Liverpool.

"I spoke with him and I think he played a big role in me coming to Liverpool and I want to thank him for all the confidence," the striker, who will wear the number 19 shirt, told LFCTV.

"He said he wanted me to come and I didn't try to ask myself questions as I was convinced Liverpool was the right club for me. It is the right club, right coach and right moment to change.

"But I want to thank Southampton because they were amazing and if I am here today I can say it is because of Southampton. I learned a lot and I worked with some nice people."

Liverpool's players who have not been involved in the European Championships are due to return for pre-season training on Saturday with their first friendly the following Friday at neighbours Tranmere.
Completing a deal before then was important for Klopp and Mane.

"I am happy because it is not easy if you start after (pre-season has started)," added the forward. "But I have signed today so I will start with the team, which makes me happy and makes it easy to work with my team-mates.

"Today is a big day and I am very happy to sign for one of the biggest clubs in Europe. It's a club that has won a lot of trophies and has a big history.

"I remember when I was younger I watched Liverpool v AC Milan (in the 2005 Champions League final): it was amazing and I was happy for Liverpool.

"They had great legends like (Steven) Gerrard and (Jamie) Carragher.

"It was my dream to play at a big club and the dream has come true. I am very happy to be part of Liverpool.

"I am excited to play at Anfield in front of the amazing fans and I am looking forward to a great season together as a club. I want the fans to be confident and I think this season will be special."
