With the usual caveat firmly placed on the table that it was a Championship side that Arsenal thumped 5-0 in the Carabao Cup, there is an abundance of positives that can be taken from the game.
So many players put in pleasing performances that one can easily identify a long list of positives that can be taken from the game and the hard task is compacting those positives into a list of just five.
This one is very obvious, he had a great return to action and even scored a goal just a minute after he assumed the Arsenal captaincy, following the substitution of Mesut Ozil. He played as if he had never been away and either Sokratis or David Luiz are going to have to make way on Monday evening.
A very fine performance that included three assists but this has not been his only good performance, he has impressed every time he has been called upon and it would be harsh on him if he is benched for the United game.
What a great debut, watching him fly up the flanks with control and actually cross the ball was a sight to behold, for others that may be normal practice but for Arsenal fans, it is not something we have seen a lot of in recent times. You can clearly see that he is going to have a huge impact down the left-hand side, and the fact that he can actually defend as well is another bonus.
This young lad has a great future ahead of him and it seems to me that with careful handling and selective opportunities that he is being groomed as the long term replacement for Pierre-Emerick Aubameyang. He is clinical, has great judgement and you just know there is far more to come.
He is just getting better and better, he is showing growing maturity in midfield and while he is not quite there yet he has all the attributes to be the box to box midfielder we have been crying out for since Aaron Ramsey left for Juventus.
