Arsenal succumbed to a 3-1 defeat at league leaders Chelsea on Saturday that surely ended their slim hopes of landing the Premier League title.
After falling behind to a Marcos Alonso header, the Gunners never got a foothold on the game. Eden Hazard widened the gap before former Arsenal midfielder Cesc Fabregas added to the heartache with the third.
Substitute Olivier Giroud did nod home a late consolation, but it won't have eased the pain. Arsene Wenger is now facing a gruelling battle for a place in the top four, with both Manchester clubs likely to take heart from Arsenal's recent poor form.
