Arsenal Video: Watch Carl Jenkinson Tally Horrific Own Goal in Gunners' Victory

Carl Jenkinson is young, and he'll learn, but yesterday's match is one the defender would love to forget.

Arsenal is preparing for the season with a tour in Germany, and with the Gunners holding a commanding 2-0 lead, the ball got flipped in to Jenkinson, who tried to boot the ball away.

Afterward, he could only watch it sail towards the net, putting Arsenal in danger.

Naturally, the keeper wasn't prepared for such a volley and recoiled in horror.

The ball continued to sale right into the net, giving the hosts a goal without doing any work to earn it. Jenkinson stood in complete disgust, wondering how that ball found the back of the net.

It was shoddy defending to have played the ball the way he did, but these are the growing pains you experience with a young defender.

Despite that, Arsenal won 2-1 thanks to two beautiful goals from Gervinho, Wenger's latest signing.

The Ivory Coast national made his debut for the Gunners and did so in spectacular fashion, lobbing the first in with a sublime first touch off of the pass, and the second came soon after, as he forced his way to the front of the net and powered it by the keeper.

Jenkinson's blunder was the only blemish on a great match, and it's sure to draw ire from Arsenal supporters, who are tired of Arsene Wenger's frugal, young defensive signings in the transfer window.

The Gunners have had issues defensively, and this own goal isn't going to inspire confidence from the fanbase, who wants silverware after a lengthy drought.

This was an unfortunate incident, and it can happen to the greatest defenders, but you can count on this being a learning experience for Jenkinson.

Few managers get the most out of young talent like Wenger does, and he will be in his young defender's ear, reminding him to avoid the situation he found himself in yesterday.

Thankfully, this was during a friendly because I would hate to see how the fanbase would react if this happened in a decisive match.
