"I think managers and the directors of football clubs are to blame for the players' football education," Shilton told BBC Football Focus.

Keown added: "What you want is people within a club to educate players and to say, 'we don't want that - we want to win but we must be fair and honest'.

"Falling over leads to other things. It does leave a sour taste in the mouth."

Manchester United winger Cristiano Ronaldo was accused of diving during his side's win over Middlesbrough last Saturday.

I think it could ruin the game Peter Shilton

Tottenham midfielder Didier Zakora appeared to fall when no contact was made to win a penalty in the 2-1 win over Portsmouth in October in one of the more high-profile cases of diving this season.

Shilton said: "Is it being a man to sort of fall over as soon as someone obstructs you?

"I watched Aston Villa the other day and some of their players were clouted and you thought they might have fallen over but they were really trying to stay on their feet.

"That is a good attitude to have. It's positive and trying to do your job right.

"If you're thinking the other way and that if someone touches you, you're going to fall over, that is negative."

He added: "I think it could ruin the game. That's one thing the fans do not like to see.

"At the end of the day football is a massive entertainment and it's a religion to some people who will watch it whatever but you have to play the game the right way."
