Styles controversially awarded Chelsea a penalty which enabled the Blues to equalise after Fernando Torres' opener, before causing confusion by brandishing a yellow card at Michael Essien - who had already been booked - but insisting it was John Terry being booked.

Referees' chief Keith Hackett, general manager of Professional Game Match Officials Limited, told Sky Sports News: "Accountability exists and we, the PGMOL, do expect referees to get big decisions correct.

"On this occasion it was wrong and therefore Rob will not be officiating next weekend."
