Galatasaray goalkeeper Fernando Muslera, a target of Premier League leaders Chelsea, is now wanted by Real Madrid.
With questions marks over the future of current number two Asmir Begovic, Blues boss Antonio Conte is keen on bringing in a back-up to Thibaut Courtois in the summer.
However, Real Madrid are also thought to be in the market for a new goalkeeper and have identified Muslera as the ideal target, according to reports in Turkey.
The 30-year-old Uruguay international's contract expires in under 18 months and he has attracted the attention of clubs across Europe.
