Ryan Bertrand is on Chelsea's radar and the Southampton star could complete a move back to Stamford Bridge in the summer.

Antonio Conte is going to be in the market for at least one full-back and Bertrand, 27, has been identified as an option.

Chelsea sold the England international to Southampton for £10 million in 2015.

He has thrived on the south coast at St Mary's and will likely cost at least double what he sold for.

Chelsea do not mind buying back players they have previously sold, having done so with David Luiz and Nemanja Matic. They are also in the mix for Everton's Romelu Lukaku.

Bertrand has made 23 starts for Claude Puel's side in the Premier League this season, chipping in with two goals and four assists.

The England defender has created 21 chances in the league but also offers a solidity in defence which has attracted Conte.

Southampton have impressed so far this campaign with Bertrand helping his team to ninth place with six matches remaining.
