Cast your mind back to just over a month ago and it was clear what Arsenal needed. They had won just one game in seven, scoring only five goals in the process and only the signing of a new striker like Ivan Toney could help their fading title hopes.
Six short weeks later, the Gunners have hit a remarkable hot streak with 16 goals in four matches. If they had scored just three more then they would have managed half as many in these four games as they had in the 20 matches prior.

Crucially, these goals have also allowed Arsenal to get their nose in front in games. Arteta has spoken about wanting to go 100mph in games only to be prevented by game state. By getting an edge in matches, the Gunners have been able to force the opposition into giving them spaces that have exploited
