Celtic passed a big test this afternoon with a solid performance to defeat the 10 men of Aberdeen.

Celtic were dominant early, creating several chances, including two big chances from Jozo Simunovic, but Celtic were unable to score until Aberdeen were reduced to 10 after a second yellow card was issued to Dominic Ball for an aerial collision with Ryan Christie, who was forced off with a nasty head injury.

Celtic finally broke through with a brilliant hit from James Forrest, who laced it into the top corner, leaving the keeper with absolutely no chance of stopping it.

Aberdeen’s Mikey Devlin shoved Jonny Hayes to the ground to give Celtic a penalty, which Odsonne Edouard stepped up and converted after 61 minutes. Lewis Ferguson was given a straight red card after a bad challenge on Tom Rogic, reducing Aberdeen to nine remaining players. Rogic found Celtic’s third goal just two minutes later after Mikael Lustig laid the ball off and Rogic eased the ball into the bottom corner.

For the first time since 1957, Celtic will face Hearts in the Scottish Cup Final on May 25.
