After a long negotiation, the Spain defender finally signed with Athletic last week, leaving Al-Nassr.
This move marks Laporte's return to Athletic, which he left in 2018 to join Manchester City.
He expressed his excitement, saying, "I'm very happy to be with you. Today is a significant day for me. We're looking forward to an exciting season, and I'm eager to play and contribute to the team at San Mamés."
Laporte also shared his gratitude, stating, "It's everything I've ever wanted. Thank you so much for your support."
The 31-year-old defender has committed to Athletic Bilbao until 2028.
