Jamie Vardy's 12th minute penalty gave the Foxes the lead after he was brought down by Ben Foster while Etienne Capoue was sent off late on for the Hornets.

Maddison's strike was redemption after he was sent off for diving against Brighton last week.

He told the club website: "It's right up there. It's a different sort of goal, it's not like an individual strike from distance or a free-kick. It was a really good counter attack, a good team goal.

"I picked it up from deep, I found Vards who was in a good bit of space and he got it out to Marc.

"The quality Marc has got from wide areas, he put it on my toe, didn't he? I had a good touch and thankfully I stuck it away. I'm really chuffed with that one.

"It was a very successful afternoon. We haven't won here since September I'm told. That's quite a long time. To get three points and a goal after last week, I'm really happy.

"That winning feeling, you never get bored of that."

Isaac Success and Andre Gray missed fine chances for the Hornets, who have won just two of their last 11 games in all competitions.

They were well beaten and their misery was compounded when Capoue was dismissed a minute from time after a two-footed tackle on Kelechi Iheanacho.

Boss Javi Gracia confirmed the club will appeal the red and also refused to criticise referee Graham Scott following the penalty.

"I saw it clear because it was in front of me, but I prefer not to say anything, only what Iheanacho said," he said.

"He said Capoue didn't touch him. That is more important than what I can say. Yes, we will appeal. It doesn't depend on me but we are going to appeal. Someone spoke with him (Iheanacho) and told me what he said.

"If I say my opinion it will sound like an excuse. I prefer to keep my opinion to myself. I prefer to do this. In the last games we have been a bit unlucky with these decisions."
