Cardiff City manager Neil Warnock has suggested Simon Hooper should not be refereeing Premier League games after his side's 5-1 thumping by Watford on Friday.

Josh Murphy appeared to be bundled to the ground just inside the penalty area by Daryl Janmaat shortly before half-time, but Hooper was unmoved.
