Chelsea continue to be linked with Southampton’s Fraser Fortser amid uncertainty over Thibaut Courtois.
Courtois has refused to offer any assurances that he will remain with Chelsea after they missed out on a place in next season’s Champions League.
Real Madrid had been heavily linked with the Belgian stopper and now Barcelona could go head-to-head with their La Liga rivals for the custodian, according Spain’s Mundo Deportivo.
The report says Forster has been identified as a potential replacement should Courtois depart Stamford Bridge, although Chelsea are also thought to be considering Stoke’s Jack Butland.
Forster himself has previously indicated he is flattered by the reported interest from Stamford Bridge but played down the suggestion he could leave St Mary’s in the summer.
