Stoke's long unbeaten home run was brought to a shuddering halt as Chelsea chalked up a 4-0 victory - with a helping hand from Jonathan Walters.
The Potters had not lost at the Britannia Stadium in the Barclays Premier League since February and have proved formidable opponents for the league's big guns, but this was their biggest home loss since returning to the top flight in 2008.
It began to go wrong in injury time at the end of the first half when Walters headed into his own net, and remarkably the striker repeated the trick in the 62nd minute. Three minutes later Frank Lampard netted a penalty after Juan Mata went down and Eden Hazard rounded off the scoring with a long-range screamer 17 minutes from time.
