Derry City winger Patrick McCourt has signed a three-year contract with SPL champions Celtic.
The 24-year-old Northern Ireland international had seemed set to join West Bromwich Albion earlier in the week, but has opted to join the Bhoys instead.
He told his new club's official website: "I'm thrilled and it still hasn't quite sunk in yet to be honest. This is a dream come true for me.
"There was interest from a few clubs, but as soon as I found out that Celtic were in for me, my mind was made up.
"I have always been a Celtic supporter and there was only one choice to make.
"To sign for this club is a dream and when I get back home, it might all finally sink in. It's just been an incredible day."
