Liverpool are closing in on their fourth signing under Jurgen Klopp after the Reds agreed a fee with Southampton for the transfer of Sadio Mane. The Senegalese attacker is expected at Anfield on Monday (27 June) to undergo a medical and discuss personal terms.

According to BBC Sport, the Reds have agreed a fee in excess of £30m ($40m) with the Saints after Klopp made Mane one of his top transfer targets of the summer. The deal for the Senegal international, if completed, will be the third highest in Liverpool's history following Andy Carroll's £35m move from Newcastle United and Christian Benteke's £32.5m move from Aston Villa last summer.

The 24-year-old forward has been impressive since his arrival from Red Bull Salzburg in 2014 and has shown that he can play all across the frontline and perform duties as both the goal scorer and the provider. Klopp had indicated earlier in the summer that he was keen to add more width to his squad in the form of wingers and in Mane he will get the perfect addition to a frontline that already includes Daniel Sturridge, Divock Origi and Roberto Firmino.

According to ESPN, the deal is likely to be concluded before the end of the week provided there are no hitches when discussing personal terms. The Saints star will become the former Borussia Dortmund manager's fourth capture following the signings of Marko Grujic, Joel Matip and Loris Karius. The latter two were signed during the January transfer window, while the Mainz goalkeeper was the first signing of the summer.

Mane's arrival is likely to further put Christian Benteke's future at the club in doubt, and BBC Sport understands that the Merseyside club are planning to recoup most of the funds paid to Southampton with the sale of the Belgian forward. The 25-year-old, who was former manager's Brendan Rodgers' marquee signing last summer has failed hold down a first-team place under Klopp and is likely to be offloaded.
