Arsenal have agreed a fee with Celtic for the transfer of Kieran Tierney, Sky Sports reports.

The Scotland international left-back is on his way to London and looks set to sign ahead of Thursday’s Premier League deadline.

Arsenal’s initial £15 million bid for Tierney was rejected in June, as was a second £25 million offer, as it contained too many add-ons and was dependent on the Gunners qualifying for the Champions League.

The 22-year-old, who has won five Scottish Premiership titles, made 40 appearances in all competitions for the Hoops during the 2018/19 campaign.

If Arsenal are able to complete the deal for Tierney, he would be Unai Emery’s fifth signing of the summer window.

Emery had said on Wednesday that the club needed a defender and they will do everything possible to sign a central back before the close of the transfer window by 5 pm on Thursday
