Leading through a penalty that was beyond dispute, Crystal Palace looked to have been denied victory by a penalty that was rather less clearcut, and their supporters would probably maintain that the substitute Lee Chung-yong’s late winner, a fine, curling shot struck from outside the penalty area, ensured justice was done. Even so, they would also have to acknowledge the debt owed to their goalkeeper Wayne Hennessey, who made a series of fine saves to keep Stoke at bay.
