Crystal Palace have reportedly begun negotiations with West Ham United over a possible deal to sign goalkeeper Adrian.
The Eagles are in the market for a new shot-stopper this summer to provide competition for Wayne Hennessey after seeing Steve Mandanda return to Marseille just a year after joining the club.
New manager Frank de Boer had been keen to bring in Jasper Cillessen as his first choice, but the Daily Mail reports that they have now switched their attention to Adrian.
The Spaniard is expected to cost £3m and is eager to leave Selhurst Park this summer having made just 16 Premier League starts last season.
Adrian's first-team opportunities are expected to become even more limited following the arrival of Joe Hart on loan, and Palace are keen to make him their third signing of the summer after Jairo Riedewald and Ruben Loftus-Cheek.
The 30-year-old has spent four years at West Ham, making 123 appearances for the club since joining from Real Betis in 2013.
