The Belgian has been in great form this season but his future is out of the club's hands.
It was a tough task at Southampton last summer. The club had to replace several big names that had left the club. Ryan Bertrand was tasked with replacing Luke Shaw, Dusan Tadic stepped into the void left behind by Adam Lallana, Graziano Pelle was asked to emulate Rickie Lambert while Ronald Koeman arrived to take over from Mauricio Pochettino and oversee the revamp.
Another top signing was that of Toby Alderweireld, who was brought in as a replacement for Liverpool newbie Dejan Lovren.
The season-long loan signing from Atletico Madrid has not failed to impress at Southampton, a fact proven by their struggles since he picked up a groin injury in January.
Alderweireld confirmed his desire to remain at St Mary’s next season to BBC Solent last month, although he admits that the decision ultimately rests with his parent club.
Now his club have confirmed that they want him back. Atletico's sporting director Jose Luis Perez Caminero telling the club's official website:
“Our coaches follow a detailed monitoring of all the players that are loaned to other teams.
“We are very pleased with their performance and growth in general. Oliver [Torres] and Alderweireld, for example, are finishing a very good season with Porto and Southampton and we are counting on them for the next campaign."
For Southampton it will come as a massive blow. The Belgian has been superb and after the mass exodus that Southampton suffered last season, they will not want to see key players depart again.
But it seems that Alderweireld is already on the way out.
