Former captain Graeme Shinnie is "back home" at Aberdeen after re-joining on a three-year deal from Wigan Athletic.
The midfielder spent the second half of last term on loan at Pittodrie, helping the Dons to third place in the Scottish Premiership and European qualification.
Shinnie, 31, has now sealed a permanent transfer to the club he represented 144 times between 2015 and 2019.
"Graeme is a captain, a real leader and is Aberdeen through and through," said manager Barry Robson.
"This is where he belongs and his impact on the team and club last year was there for all to see.
