Saints have received a club-record fee for the Senegalese forward.
Sadio Mané has signed for Liverpool after two seasons at St. Mary's.
Mané, 24, joined Southampton from Red Bull Salzburg in 2014 for a fee of £11.8m.
After scoring 25 goals in 75 appearances for Saints, he prompted Reds boss Jürgen Klopp to stump up and make the Senegalese attacker the Anfield club's all-time record transfer. It is also the highest fee ever paid for an African footballer.
Mané leaves Saints with fond memories, none fonder than his hat-trick against Aston Villa which was completed within just 176 seconds.
