With the sales of Ricky Lambert, Luke Shaw and Adam Lallana all complete new Saints boss Ronald Koeman will have a war chest of cash to fund suitable replacements.
One man who has been touted as a like-for-like replacement for new Liverpool man Adam Lallana is Serbian wide-man Dusan Tadic.
Tadic currently plays for FC Twente who came third in the Eredivisie last season. He is regarded as one of the most technically gifted players in the Dutch league, and last season was the best of his career thus far.
Premier League football fans can be forgiven for knowing little about the 25-year-old so here are 5 facts about him:
1) As stated above, he had an unbelievable 2013/2014 season in the Eredivisie scoring 16 goals and assisting a further 14 in the 33 league games in which he featured. FC Twente were the Dutch league's second highest scorers last season with 72 goals, meaning Tadic played a role in almost half of them.
2) He's versatile too. Tadic's strongest position is playing on the left-wing, but he can play in any position behind the striker. Whether it is on the right-side and cutting in onto his left-foot, or playing just behind the front man and supplying the goals and assists, he can do them all.
3) FC Twente signed Tadic from FC Groningen for €7.7 million in 2012. He made his FC Twente debut against his former club and ended up scoring two goals against them.
4) He could come cheap. Tadic only has one year remaining on his deal with Twente therefore will not command a too high a fee, in fact Eredivisie players rarely do. According to Transfermarkt his market value is £8.8 million, so anywhere between that and around £10 million should be more than enough for Southampton to pry him away from Twente.
5) He's also a prominent fixture in the national side having made 26 appearances and scoring 6 goals for Serbia.
