Inaki Williams will reportedly make his Champions League debut in Athletic Bilbao's Champions League clash with BATE Borisov on Wednesday.
The 20-year-old was recently called into the first-team squad at Bilbao and made his La Liga debut in Saturday's 1-0 defeat to Cordoba.
According to AS, Williams will remain part of the squad this week after impressing the coaching staff with his performance.
Williams, who has a Liberian mother, was born in Bilbao. His younger brother Nico is also on the books at the Basque club.
