Graham Potter has been told what to do in order to make Villa Park 'toxic' as Chelsea travel to the midlands.
His side are currently five unbeaten since changing manager in early September and have turned their fortunes around with four wins on the bounce, including back-to-back victories against AC Milan to transform the state of their Champions League hopes.
The trip to Villa Park poses a different question again though as Chelsea have to juggle injuries, a midweek match against Brentford on the horizon and taking advantage of a side that are out of form.
