That was absolutely brilliant. First half was as good as it gets. The passing and movement as well as the defensive discipline and effort. Perfect football. The second half was more subdued but utterly professional. Never gave Chelsea a sniff of getting back into it really.
Wenger deserves to get a victory like that for one of his milestones and what better than 20 years at Arsenal.
Special mention to Alex Iwobi, he could be one of Wengers greatest ever players he's produced by the time he reaches his prime.
