Kieran Tierney has broken another record this week after becoming Scotland's most expensive ever player.

The ex-Celtic defender made the switch to Arsenal this week for a princely £25m.

That deal saw Tierney overtake Oli McBurnie as the country's most valuable asset.

But the left-back wasn't finished breaking records, as Arsenal Media showed in a behind the scenes video from deadline day.

Tierney managed to break the Gunners' JUMP record at 55cm - despite an injury.

The club's previous record holder was Pierre-Emerick Aubameyang who hit 54cm.

During the 18 minute footage, Tierney can be seen telling an Arsenal medic that he'd "try and beat" the striker's jump after an initial attempt.
