Celtic have completed the signing of Northern Ireland international Niall McGinn.
Derry City boss Stephen Kenny revealed earlier on Tuesday that Celtic had won the race for the winger's signature and the Scottish champions have now confirmed the news.
McGinn has joined on a three-and-a-half year deal and will take his place in Gordon Strachan's squad when the transfer window opens on 1st January.
The highly-rated 21-year-old only moved to Derry City in January but he has produced a series of stunning performances and Celtic have been tracking his progress for some time.
McGinn, who made his Northern Ireland debut in November, has revealed that he shunned interest from elsewhere to link up with Celtic.
He told his new club's official website: "I'm absolutely delighted to be here.
Over the moon
"It's been a great season for me with Derry, and to now have joined Celtic just tops it all off.
"There was another club showing real interest. But when I knew Celtic wanted to sign me, my mind was made up. I've just been working hard and I'm over the moon to get it all sorted.
"This is a great club. I've supported Celtic since I was a boy, and the stadium is incredible.
"I've had a look around Lennoxtown as well, and it's a top-class facility. I just can't wait to get started now and get in training with all the players."
