Late in the transfer window, Beşiktaş contacted Betis to inquire about the possible conditions for a transfer of 25-year-old Colombian central midfielder Nelson Deossa. Galatasaray also had an interest in the player. No transfer was completed, and Deossa will remain with the club at least until the summer. Deossa joined Betis in August 2025, and his contract runs until 2030. In the current LaLiga season, he has made 12 appearances. The uncapped Colombian has a current market value of €9.00m, according to Transfermarkt.
