Diogo Leite, whose contract with Union Berlin is set to expire – and who has already bid farewell to the club – is the latest name linked with a potential summer move to Real Sociedad.
However, the Basque club isn't the only suitor for the 27-year-old defender; Everton, Eintracht Frankfurt, and Besiktas are also reportedly in the running for his signature.
The player's profile appears to align with Real Sociedad's needs and preferences, and the prospect of acquiring him on a free transfer only heightens their interest.
News of Real Sociedad's interest in the Portuguese defender was first reported on Thursday by Italian journalist Rudy Galetti, a renowned transfer market expert.
A product of FC Porto's academy, Diogo Leite spent the 2021/22 season on loan at SC Braga before heading to the Bundesliga.
