Crystal Palace have made their first summer signing with the arrival of Morocco centre-back Chadi Riad, in a deal worth £12m plus £2m in add-ons.
The 20-year-old, who moved to Betis on loan from Barcelona last summer before making the move permanent, has joined the Eagles, external on a contract until June 2029.
Riad made 30 appearances for Betis in all competitions during the past campaign and helped them finish seventh in La Liga.
“As a full international at just 20 years old, Chadi is an exciting young player who we are delighted to be able to welcome to the club," said Palace chairman Steve Parish.
