Chelsea have reportedly made Fraser Forster their number one target should Thibaut Courtois leave the club in the summer.
Belgian goalkeeper Courtois recently hinted that he was ready for a fresh challenge, amid speculation that Real Madrid and Barcelona are keen on his services.
Were the 23-year-old to move on, The Sun claims that the Blues intend to move for Southampton's number one stopper.
The report adds that Forster, 28, would set the West Londoners back at least £20m.
Upon his recovery from a knee injury, the England international was voted the Premier League's Player of the Month for February.
