Premier League champions Manchester City are reportedly keen on signing Atletico Madrid defender Toby Alderweireld.
The Belgian international is currently on a season-long loan at Southampton, where he has impressed for Ronald Koeman's side.
Southampton have the option to sign Alderweireld for £6m in the summer, but Atletico can cancel that clause with a £1.5m payment.
City would consider a move for the 26-year-old if his proposed switch to the Saints falls through, according to Goal.com.
Manchester United and Arsenal are also thought to be monitoring the centre-back's situation.
Alderweireld has scored one goal in 18 appearances for Southampton so far this season.
