Back-up goalkeeper Keiren Westwood is unexperienced at the top level so Brazil's number one stopper could be brought in.
The former Inter Milan star had a miserable start to life in the Premier League but he soon became one of QPR's best players last season - despite his side's relegation.
He's also currently featuring in Brazil's Confederations Cup campaign where he has put in some good performances.
Arsenal were rumoured to be interested in acquiring the 33-year-old's services, but with reports having quietened in recent weeks, Sunderland will look to swoop.
