Primera Liga outfit Osasuna have announced that Alejandro Arribas has joined the club on a three-year contract.
The defender arrives on a free transfer having spent the last two seasons with Rayo Vallecano.
The 23-year-old helped Rayo to promotion back into the top flight in 2010/11, a standing they cemented last term.
He was, however, allowed to leave the club at the end of the 2011/12 campaign.
The deal he has penned with Osasuna includes a five million euros buyout clause.
He has already passed a medical and will become the Pamplona-based club's third signing of the summer, following the arrivals of Nano and Sisi.
