Chelsea are preparing a swoop for Atletico Madrid defender Toby Alderweireld in the summer to replace the departing Felipe Luis, according to the Daily Mirror.

Alderweireld was on loan at Southampton last season and was an integral part of the team which managed to qualify for the Europa League this season, courtesy of Arsenal's FA Cup win over Aston Villa.

The Saints had the second best defensive record in the league and the Belgian played a key role in their success, which has caught the eye of manager Jose Mourinho.

Luis, who signed from Atletico in the summer, has failed to hold down a starting spot and is believed to be contemplating a move back to Madrid, with Alderweireld being sent back to the Premier League in exchange.

However, given the players Chelsea possess in their armoury, it will be difficult to get a starting spot for the 26-year-old which may prompt him to look elsewhere, with Tottenham and Southampton interested to sign him up.

The defender revealed that he would like to stay in the Premier League and insisted that he is open to teams other than Southampton should they show interest.

"I really want to go to a club that really wants me," Alderweireld said.

"There are three options - stay with Atletico, stay with Southampton or go to another club. So we will see what happens.

"Southampton gave me that opportunity and it paid off, I think. I've had a fantastic year, I can't lie about that, so, yes, I'd like to stay in the Premier League," he added.

Chelsea are looking to bring in new players to build on their title winning campaign for the season and are also keeping a close watch on Radamel Falcao to strengthen their position up front. The Colombian failed to live up to expectations at Manchester United and has had his loan deal with Monaco cancelled by the club.
