After their exhilarating 3-1 win against Leicester, Arsenal supporters were beginning to dream.

They were two points off top, Mesut Ozil was purring, Shkodran Mustafi was almost playing like a Premier League-standard defender. Anything seemed possible.

Since then, Arsenal have drawn all their of their subsequent Premier League games - including on Sunday against Wolves, where for so long they looked destined to lose until Henrikh Mkhitaryan's 86th-minute equaliser. The more optimistic fans would point to Arsenal's equaliser as a sign of their resilience, but really they were outplayed for long stretches and relied on goalkeeper Bernd Leno and then the woodwork to bail them out.

The bigger picture is that in all competitions Arsenal have won one of their last five matches, and that was a nervy League Cup defeat of League One Blackpool. Their sweeping momentum has ground to a stutter.

What’s changed then? What’s happened to the team that until a couple of weeks ago was on a run of 11 straight victories?

Looking just at the Wolves game, the most obvious vulnerability came down the Arsenal left. With Nacho Monreal still injured, Sead Kolasinac was again asked to deputise - and how brutally Wolves targeted him. Knowing that Pierre-Emerick Aubameyang would have little interest in defending from his nominal position on the left wing, Wolves’ imperious central midfield pair of Ruben Neves and Joao Moutinho took it in turns to spread the play to Helder Costa, who could isolate and sprint past Kolasinac.
