Former Celtic striker Andy Walker believes Kieran Tierney will join Arsenal.
And he is worries about the shockwaves that will send rippling through the Hoops support.
Walker said, "It will be a real downer for the fans when Kieran Tierney leaves.
"You can lose any player and fans will just accept it because that's what Celtic do so well - fatten them up and sell them on.
"But this is a young lad who is Celtic through and through. Such a talent who came through the whole system.
"I played with Paul McStay and Tommy Burns and I put him in that category.
"Kieran is a great defender but also a great attacker. They will really miss him. I'm not convinced yet about his replacement."
