Arsenal have completed the signing of Kieran Tierney..
The full-back joins on a permanent deal from Scottish champions Celtic for a fee thought to be in the region of £25million.
It brings a happy ending to a long-running transfer saga, and Unai Emery will no doubt be delighted to finally get his man.
Strengthening the defence was a top priority for the Gunners and the addition on the 22-year-old will be seen as a huge boost as they look to close the gap on the top four this term.
Despite completing his deal, it's expected that Tierney will have to wait to make his debut as he works his way back to fitness following injury.
With everything done and dusted with the deal, supporters will be keen to know what squad number they should be asking for on the back of their Arsenal jerseys.
The Gunners have confirmed that Kieran Tierney will wear the number three jersey this term.
It's a traditional number for a left-back, and the 22-year-old will be hoping to keep hold of that jersey for many years to come after completing his switch to north London.
