Arsenal had two previous bids for Tierney rejected this transfer window. But the Gunners look to have now landed their man, subject to the defender passing a medical. Celtic were holding out for a fee in the region of £25million but Arsenal were only willing to meet that sum through additional clauses. It means the Scottish champions will receive a record fee for a player sold north of the boarder.

Tierney is set to board a plane at around 9pm and will land in London tonight to sign personal terms. A medical is expected to take place tomorrow morning ahead of the 5pm transfer deadline. Celtic manager Neil Lennon spoke earlier this week as he anticipated the north London side making a late move. "I know these deals can get done at a minute to twelve," Lennon said.

"I'd be surprised if there wasn't another offer for Kieran, but delighted. "He'll be fit in a week or two. He still has some adductor pain, but I think the problem is starting to settle and he’s over the double hernia." Arsenal have been very busy in the summer market and smashed their transfer record to sign Nicolas Pepe for £72m. Dani Ceballos, Gabriel Martinelli and William Saliba also joined the club, with the latter loaned back to Saint-Etienne for the upcoming season.
