Southampton reportedly have competition for the permanent signing of Toby Alderweireld.
The Belgian defender, 26, has impressed on his season-long loan from Atletico Madrid but the Saints fear they may miss out on a less temporary deal according to the Daily Mirror.
It is believed that Tottenham and Manchester City are showing interest in the former Ajax centre-back who has made 21 Premier League appearances this campaign which has been hampered by hamstring injuries.
