Watford and Crystal Palace are reportedly set to compete for the permanent signature of Athletic defender Unai Núñez.
The 21-year-old was promoted from Bilbao's youth ranks to the senior team in July 2017 after registering 33 appearances for Bilbao Athletic (the B team). He made 36 appearances overall in his debut season for the first team, which saw him feature in La Liga, where he scored his first senior goal for the club in March.
He also played three times in the UEFA Europa League, as Los Rojiblancos reached the Round of 16 and were eliminated by eventual runners-up Marseille.
