David Moyes doubted Arsenal's title credentials back in December - and he may have just ruined them on Sunday afternoon.
For the second successive Sunday, Mikel Arteta's side relinquished a 2-0 lead away from home. But whilst their escapades at Anfield were widely seen as escaping with a point, Sunday's showing at West Ham signified a side now yielding under intense pressure from Manchester City.
Again, Arsenal controlled the early stages, with Gabriel Jesus and then Martin Odegaard putting his side 2-0 up with 10 minutes. But the tide turned 12 minutes before the break, when the home side were gifted a penalty and Said Benrahma did the honours.
