David Turnbull has completed a move to Celtic from Motherwell for a club-record fee.
The youth academy graduate leaves after 12 years at Fir Park, having joined our ranks as a nine-year-old in 2008.
He has since gone on to make 41 appearances for the club, scoring 16 goals.
While the fee can not be disclosed due to a confidentiality clause in the transfer agreement, it vastly exceeds the amount the club received for its previous record sale of Phil O’Donnell, also to Celtic, of £1.75m.
“I want to thank everyone at Motherwell, the staff, players and the fans, for everything they’ve done for me so far in my career,” said the player.
“Particularly David Henderson, who has helped me so much over the last year. I owe him so much.
“I am a Motherwell fan, so I leave with a heavy heart. But I have made memories and friends for life at a club I’ve been involved with all my life.”
Motherwell manager Stephen Robinson added: “David is a wonderful player who will go on to big things in his career.
“The staff are all delighted to have played a part in his development throughout his career to date.
“From a football perspective, it is obviously sore to lose a player of his quality. But that is the model at Motherwell. We develop players to go on to a higher level and he is another success story in that regard.
Everyone at Motherwell FC thanks David for his efforts during his long spell at the club, and wish him well for his future career.
