Hazard was sent off by referee Chris Foy for kicking Charlie Morgan in the closing stages of Wednesday night's Capital One Cup semi-final second leg at Liberty Stadium.
"Hazard toe-poked the ball under the boy's body. Why is the kid lying on the ball in the first place?" he said.
"You can imagine the frustration - you're a player trying to reach a cup final but there's this kid behaving like an idiot who won't give you the ball back.
"Hazard didn't kick the kid, he kicked the ball underneath him, but the whole thing got blown out of all proportion.
"I can think of a lot of players who would have kicked a bit harder than he did. He just toe-poked the ball away.
"The boy was tweeting before the game that he's a super time waster. The way he behaved was disgusting."
