LeBron James says he is still confident the Cleveland Cavaliers can win the NBA Finals despite the fact they are facing a do-or-die Game 6 clash with the Golden State Warriors.

The Warriors opened up a 3-2 lead on Sunday thanks to a 104-91 home win at Oracle Arena in Oakland even though James pitched in with a 40-point, 14-rebound and 11-assist performance in California.

Two-time NBA Finals MVP James can never be accused of lacking self-confidence and he insists the Warriors will not have it all their own way as the Cavaliers look for revenge for the Game 5 defeat.

The 30-year-old said: “I feel confident because I’m the best player in the world. It’s that simple.”

James has now called on his team-mates to protect their home turf at the Quicken Loans Arena as the Cavaliers look to take the NBA Finals all the way to Game 7.

The Akron-born superstar added: “We’re going home with a Game 6, and we’ve got enough to win it.

“We protect home, we come [back to Golden State]. We’ll worry about Tuesday first. But if we protect home like we’re capable of doing, we force a Game 7.”

The Cavaliers are 2.40 to win Game 6 with the Warriors 1.57 to pick up the victory that would seal the NBA Championship.

Meanwhile Warriors ace Stephen Curry feels his side have enough left in the tank to get over the line and secure the sport’s top prize.

“We fought hard all year and put ourselves in good position now to go to Cleveland and hopefully close it out,” he said. “We’re confident.”
