Arsenal is a club divided by civil war.
Tensions between the Wenger Out brigade and those loyal to the long-serving manager have reached boiling point.
Thankfully neither of the gentleman involved appeared to be capable of causing much harm but there’s no place for such disruptions inside the stadium, or anywhere for that matter.
On the pitch, a Shkodran Mustafi header earned the hosts a point after first-half goals from Leroy Sane and Sergio Aguero had put City in the ascendancy.
Theo Walcott was also on the scoresheet and appeared visibly annoyed at Arsene Wenger’s decision to substitute him off for Alex Iwobi in the second half.
