West Ham United have signed Athletic Club left-back Adama Boiro on a season-long loan deal, with an option to buy.
The 24-year-old has played 45 times for the Basque club, including six appearances in last season’s Champions League.
“I like the challenge that’s in front of us here,” Boiro told West Ham’s website.
“This is a club with ambition and an objective to get promoted, and I think my mentality, my desire and my hard work will help my team-mates and the club achieve that.”
Boiro becomes West Ham’s ninth signing of the summer transfer window, following Venezuela midfielder Keiber Lamadrid, Dutch defender Joel Veltman, Israel winger Manor Solomon, Belgium midfielder Arne Engels, Suriname striker Joel Piroe, England Under-19s midfielder Divine Mukasa, Norway Under-21s winger Edvin Austbo and Brazilian defender Morato.
