Derby County captain Richard Keogh has warned Chelsea players not to dive ahead of their Capital One Cup tie.

Keogh witnessed the Chelsea performance branded 'Swan Lake' by Hull manager Steve Bruce and is not afraid to deliver personal rebukes to offenders.

"I stick up for my team-mates, I stick up for the club," said Keogh.

"Players are going to do it unless their manager stamps it out. It will be a touchy subject for as long as it carries on. You don't want fellow professionals to cheat.

"I don't know if cheat is the right word, it is one of those things that happens in football that we want to see less of.

"The referee is the key to it. He has to be strong. It is such a tough decision because the pace of the game means things happen so quickly. Players can't argue if they have blatantly dived and get booked - it is not right."
