Chelsea are lining up replacements for the possibly departing Thibaut Courtois this summer, with Southampton goalkeeper Fraser Forster reportedly the most recent one.
According to The Sun, Forster is also being targeted by Barcelona, as Marc-Andre Ter Stegen looks to leave the Spanish giants this summer.
However, Chelsea look like to be on the pole position to sign the England international with the club monitoring a £20 million bid for the goal stopper.
Courtois has recently showed uncertainty over his Chelsea future, linking him into a move to Santiago Bernabeu with the La Liga side showing a lot of interest for the Belgian.
Real Madrid are thought to be preparing a world record £79 million for the 23-year-old and Chelsea have moved fast to make plans should he move.
Forster has been impressive for Southampton after returning from his serious knee injury this season, not conceding a goal in 708 minutes and winning the Player of the Month award in February.
