The Republic of Ireland interantional only moved to the KC Stadium in January for £7.5m from West Brom and scored four goals in 15 games for Steve Bruce’s side.
Saints’ new manager Ronald Koeman wants the 27-year-old to form a strike partnership with Italian Graziano Pelle, who followed the Dutchman from Feyenoord.
Koeman made the former Reading forward his number one target after Manchester United’s Javier Hernandez apparently rejected a move to the south coast club.
The Mexico international has been told he can leave United, but is keen to move to a club playing in Europe.
Long‘s possible arrival at St Mary’s follows the departures of Adam Lallana, Rickie Lambert, Luke Shaw, Dejan Lovren, Dani Osvaldo and Callum Chambers.
Not saying Liverpool fans cant ever comment but consider the similarities: Club overpays for player after selling player(s) and getting massive amounts of money, which everyone knows they have and everyone knows they need to buy. Its not simply a bit similar, its exactly the Liverpool - Torres - Carroll situation again. Therefore Liverpool fans, like dooby, cant really have a go at Southampton.- Nutboy
