Marley Watkins has signed a two year deal with the Dons.
He re-joins the club on a two-year deal.
Marley spent the first half of last season on-loan at Aberdeen from Bristol City. The Welsh attacker impressed but injury curtailed his loan. He joined Cardiff City on a deal until the end of August.
Stephen Glass explains: “I’m delighted Marley has chosen to return to the Club.
“In his previous spell at Aberdeen his influence on the team was enormous and we are looking forward to having him back in a red jersey. I expect the fans will be delighted to see him back with the Club.
“We have beaten off a lot of competition for him and I am sure he will enjoy a great reception upon his return to Pittodrie.”
