With both Manchester clubs starting with defeats from their opening Champions League ties, Arsenal and Chelsea were hoping for better fortunes as they travelled to Dinamo Zagreb and hosted Maccabi Tel-Aviv, respectively.
The Blues delivered with ease, brushing their opponents aside with goals from Willian, Oscar, Diego Costa and Cesc Fabregas. Eden Hazard's missed penalty and an injury to goalscorer Willian were the only downers for Jose Mourinho's men.
However, it was a considerably less comfortable night for Arsenal, as they got their campaign off to the worst possible start with a 2-1 defeat in Croatia.
