Scotland international Stuart Armstrong has joined Aberdeen on a two-year-contract.

The 33-year-old, who spent his school years at Hazelhead Academy in the City, was most recently with Sheffield Wednesday in the English Championship.

Capped 51 times by Scotland and having clocked up almost 150 games in the English Premier League, the energetic and experienced midfielder will add further competition to the Dons squad for both European and domestic fixtures.

“We have been tracking Stuart for some time, and we are so pleased to be able to add a player of his talent and experience to our group,” Dons boss Jimmy Thelin said.

“Stuart has had an impressive career at the top level of the game, and we hope he can act as another leader in our squad.

“With such a busy schedule coming up, we want to drive competition in all areas of the park who can bring different attributes to how we play.

“We also have several very talented young prospects and having a core of experienced players from Scotland to help them develop has always been part of our strategy.”

Stuart played some of his youth football at Dyce Boys Club then Inverness CT before breaking through at Dundee United.

He enjoyed a successful six-years on Tayside before joining Celtic in January 2015. He won eight trophies at Celtic Park, including four league titles, two League Cups and two Scottish Cups before moving to Southampton in June 2018 for a reported fee of £7m.

He would spend six seasons at St Mary’s, amassing an impressive 215 games scoring 25 goals and assisting 25.

He left last autumn for a short spell in Canada with Vancouver Whitecaps before seeing out the latter part of 2024-25 at Hillsborough.

Having sealed his move to the North-east, Stuart said:

“These things always happen fast but I am delighted to be here.

“I’ve not been back to the city for a long time so it’s nice to come back full circle in a football sense which is nice.

“It’s a good footballing decision for me to come here. It’s a chance for me to play competitive, challenging football and the lure of playing in Europe is exciting.

“I hope I can add something to the team and help us achieve something special together.”
