Former Celtic and Arsenal player Charlie Nicholas believes the Hoops could sell Kieran Tierney for £20m.

Arsenal have already had a bid rejected for the 22-year-old, with the Scottish champions believed to be holding out for £25m.

However, Nicholas says he has heard rumours that Tierney is interested in making a move South, and Celtic may sell up if the Gunners make an improved offer:

“The stories I’m hearing here in Glasgow is that he might be keen to move on to the bigger league if that’s really what it’s about. Would that make him a better player? Probably.”

“There is a question mark about his defensive frailties but then again he would be an improvement for Arsenal, there’s no doubt in my mind about that.”

“Tierney is a fabulous footballer, but he’s got a lot to learn defensively and that’s the issue in value. So I think if Celtic got £20m, they would take it.”

It would be a surprise if the defender is angling for a move away from Parkhead this summer.

Tierney grew up supporting Celtic as a child and signed for the club at the age of seven. He has established himself as a key first-team player but it appears his head could have been turned.

Whether the Scottish club would sell up for £20m, as Nicholas says, we shall have to wait and see. Arsenal are said to be looking to offer £19m for the fullback, and Celtic fans will be hoping that the bid is turned down.
