Boos rang around Stamford Bridge as Potter's side fell to a fourth home loss since the manager took charge in September, a result which saw them slip below Villa into the Premier League's bottom half. The result saw bookies slash Potter's down to 2/1 to be next manager to go, when he had drifted out into double figures during March after victories over Leeds, Dortmund and Leicester.
The Toffees will go into the game unbeaten in their last three.
