Celtic have confirmed the signing of Hibernian midfielder Scott Allan on their official website, with the 23-year-old penning a four-year deal.
Allan has become Celtic's fifth signing of the summer, joining Logan Bailly, Saidy Janko, Dedryck Boyata and Nadir Ciftci in joining Ronny Deila's side.
The midfielder, who starred in Alan Stubbs' side having joined from West Bromwich Albion last summer, will now compete with the likes of Nir Bitton, Scott Brown, Charlie Mulgrew and Stefan Johansen for a place in the Celtic midfield.
The move has been shrouded in controversy, given that - as reported by STV - Celtic's Old Firm rivals Rangers have had three bids rejected for Allan, who told the Daily Record just last year that his dream was to play for Rangers.
Instead, Allan has now joined their arch-nemesis Celtic in a surprise move, and told the club's official website that he can't wait to get stuck into 'exciting challenges' under Ronny Deila.
"I am absolutely delighted to sign for Celtic, such a fantastic club," said Allan. "It is such an honour to be given this opportunity and I can’t wait to get started and play my part in bringing success to Celtic and our supporters.
"There are so many exciting challenges ahead for us now in Scotland and in Europe and I am looking forward to being part of all that lies ahead. I know a number of players well at the club already, so it will be great to team up with these lads again as well as all my other new team-mates, and I know we will work hard together to bring more good times to our fans."
"I know the high-quality of players at the club and I know it will be a big personal challenge for me but it’s one I’m ready for and one I am relishing. I would like to thank the many fans who have already welcomed me to the club. I really appreciate this support," he added
Allan is now loved by one half of Glasgow and loathed by the other, but will have to put all the off-field controversy out of his mind in order to be a success at Celtic.
As for manager Ronny Deila, he has now snapped up another talented young Scottish player, having landed Stuart Armstrong and Gary Mackay-Steven in January - and building a team of Scottish players for now and the future is just what Celtic fans want to see.
