The Frenchman received two yellow cards in the space of 16 minutes to receive his marching orders in Arsenal’s Champions League opener.

Arsenal striker Olivier Giroud must be enduring the worst, most stressful spell of his career in north London.

The French forward, despite scoring in the club’s 2-0 win over Newcastle last Saturday, has failed to spearhead the club’s attack as the fans would have desired, with only two goals to his name so far this season.

And on Wednesday, things turned out for the worse when he was named in the Gunners’ starting lineup for their 2015-16 Champions League opening game.

Arsene Wenger’s crew traveled to Croatia to lock horns with Group F opponents Dinamo Zagreb, but things quickly fell into a downhill spiral for the Premier League side.

After only 24 minutes of play, Arsenal were trailing the home side 1-0 after a cleared ball rebounded off Alex Oxlade-Chamberlain into the back of his team’s own net.

16 minutes later, and the Gunners were down to ten men. Giroud, having picked up a booking a minute prior to Arsenal’s own goal, received a second yellow with only 5 minutes remaining on the first-half due to a late, above-the-knee challenge on one off the opposing players.

His third red card since arriving at the Emirates back in 2012, Giroud left the pitch, with many on Twitter slamming the already under-fire attacker. Check out some of the best tweets below.
