It's been quite the summer for Southampton. An eighth place finish was fantastic for the Saints in just their second season back in the Premier League, but they paid for that success. Manager Mauricio Pochettino left the club for Tottenham, whilst they also lost Calum Chambers, Dejan Lovren, Luke Shaw, Adam Lallana and Rickie Lambert as the biggest teams in England picked off the best talent from the South Coast.
Lovren has been replaced by Atletico Madrid's Toby Alderweireld, Chelsea left back Ryan Bertrand has arrived on loan in place of Shaw, whilst the target man role previously filled by Lambert is now Graziano Pelle's job. Dusan Tadic arrived from Twente as a replacement for Lallana, but manager Ronald Koeman acknowledged the England international's contribution be signing another possible replacement - Sadio Mane.
Mane, 22, has been starring with Red Bull Salzburg since he signed from Metz in 2012, with a host of English clubs monitoring his progress. With a staggering 45 goals in 87 games in Austria, Mane has been prolific to say the least, and his pace and dribbling have been too much for defences there to handle.
Something Southampton have lacked is pure pace. Lallana, Jay Rodriguez and James Ward-Prowse are all technically gifted, but aren't much of a threat in behind. This has been important to Koeman before, particularly with Feyenoord winger Jean-Paul Boetius lit up the Eredivisie with a number of dazzling performances on his way to 11 goals and nine assists last season.
Senegalese international Mane will now be tasked with replicating that success, and if he can contribute those kind of numbers in the Premier League, the Saints will feel that it's £10m well spent. It's a gamble to pay so much for a player who hasn't done much outside of Austria, but he has the raw ability to be a factor - even if only from the bench.
He may be a different player than now-Liverpool star Lallana, but if Mane can acclimatise quickly to English football, then he may help Southampton fans forget about the loss of the England international.
One thing is for sure though - supporters have to hope and pray that he doesn't end up being the next Emmanuel Mayuka, who was exceptional for Zambia and Swiss side Young Boys, only to be a huge failure at St. Mary's Stadium.
