Toby Alderweireld: Undergoing medical

Atletico Madrid defender Toby Alderweireld and Salzburg striker Sadio Mane are undergoing medicals ahead of moves to Southampton.

Belgium international Alderweireld has been linked with several Premier League clubs this summer, with Arsenal, Newcastle United and West Ham United reported to have shown an interest.

However, Alderweireld - seen by Southampton as a replacement for Dejan Lovren, who joined Liverpool earlier this summer - is now holding talks over a season-long loan move to St Mary's as Saints boss Ronald Koeman tries to complete two signings on the final day of the summer transfer window.

Southampton have offered Austrian side Salzburg £11.8million for Mane, a Senegal international.

Mane, who represented his country at the 2012 London Olympics, moved to Salzburg in September of that year from French club Metz.

Last season the 22-year-old was a major figure, scoring 13 goals as Salzburg clinched the league and cup double in Austria.

Koeman told Dutch website Helden Online: "I am still looking to bring in two more players, an attacker and a defender.

"Toby Alderweireld will undergo a medical today. Hopefully we can also add another attacker. I can't say who we are working on."

Koeman also confirmed that he has not considered a move to sign Ajax goalkeeper Kenneth Vermeer, who is expected to join Feyenoord.

He added: "We didn’t think about Kenneth Vermeer. We have bought Fraser Forster, who is 26-years-old and a fantastic goalkeeper, who is part of the England squad."

The Dutchman also acknowledged that deals for Aston Villa defender Ron Vlaar and Dynamo Kiev forward Jeremain Lens ‘didn’t succeed’, and that he opted against an approach for Queens Park Rangers new boy Leroy Fer due to the number of midfielders already at his disposal.
