Aberdeen manager Craig Brown has made his first summer signing after recruiting French defender Youl Mawene.
The 31-year-old previously worked under Brown at Preston and has also had spells with Derby and Greek outfit Panserraikos.
Mawene has signed a pre-contract agreement for now and will officially join the Dons next week.
He told the club's official website: "I thoroughly enjoyed my time with Craig at Preston. He is a fantastic coach and really sold Aberdeen as a club and a city to me when I was on trial here recently. After my experiences in Greece I can't wait to get started."
