But Chelsea were far from perfect, with Willian and Costa booked for diving and Gary Cahill lucky not to be sent off. The England defender had already been shown a yellow card for a late challenge in the first half - a tackle on Sone Aluko that Hull manager Steve Bruce thought was deserving of a straight red - and after the break the centre-back went to ground too easily inside the Hull box.
Hull's incensed players surrounded referee Chris Foy, arguing Cahill should have been shown a second yellow for diving, but the Chelsea player escaped punishment and less than 10 minutes later a frustrated Hull were reduced to 10 men.
Getting an helping hand I see, like a few times this season. Will this be highlighted, I'm sure it will by our impartial media.
