West Ham complete their first signing of the summer after the club announced the signing of Roberto on a free transfer.
The Hammers needed to sign a back-up goalkeeper for Fabianski after Adrian was released by the club. They have moved in quickly and signed the Spanish goalkeeper for free.
The 33-year-old keeper will join the Hammers on 1st July after his contract with La Liga club Espanyol expires. He has signed a two-year deal with the London club with the option of extending to further 12 months.
The vastly experienced keeper has played in Greece, Spain and Portugal, and won six trophies in his career.
