Kieran Tierney broke Arsenal’s vertical leap record during his medical on Thursday, outdoing Pierre-Emerick Aubameyang by a centimetre.

One of the checks players undergo with Arsenal during their medical is the vertical leap test. The test involves evaluating how high a player can jump without a running start and without their hands leaving their hips.

In Arsenal’s behind-the-scenes video of Tierney’s deadline day move, they show his attempt at the test. One of the staff behind the camera confirms that 54cm was the previous record – set by Aubameyang – before Tierney goes on to achieve 55cm.

Watch from 3:30 in the below video:

Standing at 5’10”, Tierney needs to be able to get off the ground well in order to effectively defend crosses and set-pieces. It doesn’t seem like the left-back is going to have any trouble in that regard, which is good news.

Tierney isn’t quite fully fit after his recent injuries, so we’ll have to wait another 4-6 weeks before he’s back out on the pitch.

With Sead Kolasinac’s off-field problems also depleting Arsenal’s left-back options, Nacho Monreal is going to be invaluable for the next few games. Once Tierney is back, however, it shouldn’t be long before he starts to push to make the position his own.
