Inter have completed the purchase of Spanish goalkeeper Josep Martinez (26) from Genoa on a five-year contract, the Serie A champions confirmed on Tuesday.
The club did not provide any details about the transfer, but Italian media suggest the deal is worth in excess of £15million.
Martinez was a key player for Genoa in the league last season, keeping eight clean sheets and helping the newly promoted club secure a surprising 11th-place finish.
It is expected that Martinez will initially play as a reserve to Inter's 35-year-old goalkeeper Yann Sommer before gradually assuming the first-team spot after next season.
Inter have lacked a backup goalkeeper since they decided not to sign Emil Audero on a permanent deal from Sampdoria, following a season-long loan spell.
