Tuesday night was just a disastrous night all round for Arsenal; not only did they fall 3-0 to Championship outfit Sheffield Wednesday, they also lost Theo Walcott and Alex Oxlade-Chamberlain to injury.
Arsene Wenger decided to field a highly experimental midfield with Alex Iwobi and Glen Kamara starting while Ismaël Bennacer and Krystian Bielik were introduced off the substitutes bench.
While the young guns endured a tough night at Hillsborough there was one player in particular who was received special criticism from Arsenal fans after the game.

Joel Campbell, making just his second start of the season for the Gunners, was slammed by a fan on ArsenalFanTV after his poor display in Yorkshire.
The supporter said: "Joel Campbell, I don't know how he is getting a shirt. I swear to god he won his place in a competition.
"How is he a footballer? He plays so well internationally but when he comes to us. I don't know if it's confidence. It's poor really."
And it appears he was not the only person to question what Campbell brings to Arsenal, with many fans taking to Twitter to voice their opinions on the Costa Rican international.
With Walcott and Chamberlain joining Aaron Ramsey in the treatment room, the 23-year-old could find himself more involved in the coming weeks. However, he will have to vastly improve on his showing against the Owls.
Campbell has been a peripheral figure at the Emirates since the 2014 World Cup and the coming months could be a make or break time for the forward.
