Stephen Curry expressed his gratitude for the support of LeBron James and Dwyane Wade after he led the Golden State Warriors past the Houston Rockets and into the Western Conference Finals.

Warriors star Curry was held scoreless in the opening two quarters of Game 6 against the Rockets at Toyota Center on Friday but produced a sensational second half, racking up 33 points to inspire the defending NBA champions - who were without the injured Kevin Durant - to a 118-113 victory and a 4-2 series success.

That haul represented Curry's best since the opening game of the playoffs, and comprehensively silenced any doubters.

And Los Angeles Lakers star James, who faced Curry in each of the past four NBA Finals during his time with the Cleveland Cavaliers, voiced his backing of his fellow three-time champion, as did retired Miami Heat legend Wade.

James posted on Twitter: "NEVER underestimate the heart of a Champion!!!!"

Wade added on his account: "Y'all better stop disrespecting @StephenCurry30 just because he's a team first guy and is willing to sacrifice in moments doesn't mean he's not still a beast."

Asked if he felt he had been disrespected or underestimated ahead of Game 6, Curry took a long pause before responding.

"I've heard a lot of noise this series, for sure, I'll just leave it at that," he said.

"Whether it's positive, negative, whatever the case is, I know what I'm capable of and it's bigger than me, so I don't get caught up in that.

"I don't need any extra motivation, I don't need to hear who I am as a player, I know that. My confidence never wavers in those situations so I appreciate those words.

"Champions recognise champions and what it takes to win games like tonight and do what we've been able to do over these last five years so hopefully [there is] more of that to come."
