HNK Rijeka goalkeeper Simon Sluga is attracting Premier League interest.
Goal says newly-promoted Norwich City and Sheffield United are reportedly leading the race to sign Sluga.
The Croatia international would be available this summer for £1.8million.
Derby County, Dinamo Zagreb and Hertha Berlin have also expressed their interest in the 26-year-old.
Norwich have also been linked to a move for Liverpool's back-up keeper Simon Mignolet.
