#4 Flop: Sokratis Papastathopoulos
Since the start of the season, injuries coupled with horror shows at the back have limited Arsenal's all-round game to mere spark in attack. Their backline has to improve by a significant margin if they have to bid for a place in the Champions League spots.
Arsenal's center-halves are just not working as a duo, and are fairly struggling against the pace and tactics of various counter-attacking oppositions. The same followed suit this time around, as David Luiz and Sokratis were caught off guard a handful of times.
They could have done much better in winning the first ball during the corner as well, which in turn was a routine off the training ground.
Sokratis couldn't keep at pace with Mousset, who threatened down the channels with willing runs and darts. He wasn't sharp enough or clinical with his tackling either. It's time Rob Holding receives the license to express himself at the heart of the Arsenal shield.
