Atletico Madrid contact Chelsea over Toby Alderweireld?

Atletico Madrid have reportedly contacted Chelsea over defender Toby Alderweireld.

Reports have suggested that the Premier League champions are interested in signing the 26-year-old, who spent last season on loan at Southampton.

It is thought that Ronald Koeman's Saints retain an option to purchase the Belgian international for close to £7m, but Madrid can halt those plans by paying a £1.5m fee to remove the clause.

According to Get West London, Atletico have offered Alderweireld to Jose Mourinho's side and are monitoring the situation of Blues full-back Felipe Luis.

Luis joined Chelsea from Atletico last summer but has been linked with a move back after failing to hold down a starting place at Stamford Bridge.

Alderweireld played 28 times for Southampton last term.
