Scottish defender Kieran Tierney’s move to Arsenal is gradually nearing perfection as the player is now in London undergoing a medical with Arsenal ahead of his transfer from Celtic.

Sky Sports reports that Arsenal agreed a fee with Celtic on Wednesday for the Scotland international left-back.

Arsenal’s initial £15m bid for Tierney was rejected in June, as was a second £25m 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.
