#4 Shkodran Mustafi
Shkodran Mustafi put in a solid shift at the heart of defence alongside Rob Holding, which is admittedly a rare sight. The latter was far from what the Arsenal faithful wish for him to become, but Mustafi on the evening, was robust across the backline.
While Holding looked a tad shaky at times, Mustafi was there to make up for his rustiness and cover-up as a foil.
In possession as well, the German was much better, as he kept the momentum going with neat and safe distribution. A slide-rule through pass to Hector Bellerin in the second half led to a fine opening, although Arsenal couldn't capitalize and make it count.
In the air, Mustafi was clearly the best of the lot as he won almost every aerial duel and out-muscled the opposition forwards. However, in order to make his performance a more notable one, he really should have done better with the header late on - a chance that was a potential winner at the time.
He is not quite there in terms of preference and consistency but is more than a handy asset in European games.
