Celtic and Arsenal have agreed a Scottish transfer record fee of £25m for
Scotland left-back Kieran Tierney.
The Premier League club have already had two bids rejected by the Scottish champions but a deal has been struck for the 22-year-old.
Tierney will now travel south to discuss personal terms ahead of the English top-flight transfer window closing at 17:00 BST on Thursday.
He last played for Celtic on 4 May due to injury.
Speaking immediately after Celtic ’s 1-1 draw away to Cluj in Champions League qualifying, Parkhead manager Neil Lennon said: “I don’t know anything. I’ve said the last few days it wouldn’t surprise me [if Arsenal came back in for the player].
“If he goes, he goes with everyone’s best wishes. He’s an outstanding talent and a great kid.”
