Zaha is being accused of diving in games this season.
"I don't know why or where it comes from, but it is outrageous to accuse him of being a diver. It's total nonsense.
"I'm not sure some of the pundits pointing the finger at Wilf even know the rules. What are they watching?
"The penalty we were awarded against Manchester City on Sunday was nailed on. Wilf can't carry on running. He can't stay up. He's in front of Sterling who pulls his arm and falls on him. Look at the picture. How is that not a penalty?
"It's nonsense to claim he dived. If he could have stayed on his feet, he would have done.
"Trust me, Wilf is a genuine kid, a genuine player who just loves to play. He is an extraordinary talent - irreplaceable for us and I can't even begin to put a value on him - and one I hope fans of all clubs enjoy watching. The reason he has won three penalties for us this season is because he's such a good player."
