For Arsenal fans it was the end of a desperate 56-day wait for a Premier League victory; for Chelsea fans the perfect way to ruin a Christmas break.
Frank Lampard's side would have gone second with a win at the Emirates but instead turned in a poor display in a 3-0 defeat that leaves them outside the top six.
Lampard called out his side for lacking energy and desire, while Mikel Arteta admitted that his Arsenal side "have let the fans down for many weeks."
So where do they go from here?
