Sunderland hope to fight off interest from West Ham United to land Fiorentina fullback Marcos Alonso.
The Daily Mail says the Black Cats had suggested a swap deal for Alonso, who made 20 appearances at the Stadium of Light last season, with Modibo Diakite moving in the opposite direction.
However, Fiorentina are more interested in a swap plus £2million cash after French defender Diakite spent part of the campaign on loan there.
West Ham and Swansea have also shown interest in 23-year-old defender Alonso, especially if the Hammers fail in their bid to land Nice left-back Timothee Kolodziejczak.
