Inter Milan and Genoa have confirmed they have swapped ownerships of Emiliano Viviano and Juraj Kucka, but both players will stay at their current clubs on loan.
Kucka only moved to Italy from Sparta Prague in January, making 18 appearances for Genoa last season.
However, the 24-year-old Slovakia international has now signed a five-year deal with Inter but will remain at Genoa until at least January.
Italy goalkeeper Viviano meanwhile will remain in Milan until at least the New Year as he recovers from an anterior cruciate ligament injury suffered during pre-season.
The 25-year-old has spent the last two seasons at Bologna in a co-ownership deal before Inter bought his full registration earlier this summer.
The futures of both Kucka and Viviano will be reassessed during the January transfer window.
