Striker Adam Rooney has joined Aberdeen on a two-and-a-half-year deal after his exit from League 1 side Oldham.
The 25-year-old Irishman heads to Scotland after spending the first half of this season with the Boundary Park side, who he joined last summer.
Rooney, who was recently released by the Latics, will be included in the Dons' squad for this weekend's game against Motherwell.
Manager Derek McInnes told his club's official website. "Adam is a proven goal-scorer and he has the quality to add something to our team.
"There were other clubs keen to take him and it's great that he wants to be part of what we're doing here at Aberdeen.
"I've said all along that I'll only bring in players who I believe will add something to the squad and Adam certainly ticks that box."
The Dublin-born player has also played for Stoke, Birmingham and Inverness among others.
