Besiktas defender Domagoj Vida has reportedly emerged as a potential transfer target for Watford.
After an inconsistent second half to the campaign, Watford are looking to strengthen their squad during the summer and it appears that they could look to bring in an addition to their backline.
According to Fanatik, Watford are considering whether to bid €4m (£3.52m) to sign the Croatia international, who has struggled for game time at the Turkish giants.
Besiktas only moved to sign Vida at the start of 2018, but the 29-year-old made just seven appearances during the closing months of the season.
Vida has won 58 caps for Croatia and has been selected to represent his national team at this summer's World Cup.
