Arsenal attacker Gabriel Martinelli has assured fans that he "feeling fine" after going off injured in Tuesday's EFL Cup quarter-final defeat to Manchester City.

The Brazilian youngster was making his first start for the Gunners for over nine months following a serious knee injury and enjoyed a bright first half at the Emirates, bagging the assist for Alexandre Lacazette's equaliser.

However, Martinelli soon went down after a challenge from Zack Steffen, and while the teenager tried to come back on for the second half, he had to be swiftly substituted.

Arsenal went on to lose 4-1 on their own turf, but Martinelli took to social media after the game to reassure fans that his injury is nothing serious.

The former Ituano man shared a photo of the game on Instagram with the caption "Feeling fine and ready to go again." ahead of Arsenal's Boxing Day showdown with Chelsea.

While Martinelli's return has been a significant boost to Arsenal, Mikel Arteta has insisted that the Gunners cannot view the 19-year-old as their saviour amid fears of a relegation battle.
