The Swedish youth international has just recovered from a serious leg break.
Plenty of young players have come through the ranks at Arsenal in recent years. The likes of Hector Bellerin, Francis Coquelin and Kieran Gibbs are all currently in the first-team picture.
Of course, not all the youngsters make it at Arsenal.
One who didn't, despite showing early promise, was Kristoffer Olsson. The young Swede played in the League Cup against West Brom in 2013, scoring in the subsequent penalty shootout.
A year later, and with no further appearances to his name, he joined Danish side FC Midtjylland on loan for six months. After impressing, he signed a permanent deal with the club last December.
Unfortunately he suffered a serious leg break five months ago, which certainly held back his progress this term.
But he returned to action at the weekend and today played his second game for the club in his comeback - what a game it proved to be.
Midtjylland drew 0-0 with Vestsjaelland this evening, a result that was good enough to secure the Danish Superliga title for the club.
The former Arsenal talent has posted plenty of pictures on Twitter celebrating the triumph and will be hoping to play a more pivotal role in their defence of the title in 2015-16.
