Former Celtic midfielder Stuart Armstrong has signed for Aberdeen.
The Scotland star was a free agent after leaving Sheffield Wednesday earlier this summer and therefore was able to find a new club after the transfer window had closed.
Jimmy Thelin has moved to add him to his squad after completing the deadline day signings of striker Kevin Nisbet from Millwall and Swedish winger Jesper Karlsson on loan from Bologna.
Armstrong has signed a two-year deal at Pittodrie.
Thelin told the Aberdeen website: “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.
“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.”
Armstrong added: “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.”
