Los Angeles Lakers superstar LeBron James said he retains a "burning desire to win trophies" in an ominous sign ahead of the upcoming 2021-22 NBA season.

James is entering his 19th season aged 36 and following an underwhelming 2020-21 campaign, which saw the Lakers dethroned after bowing out of the playoffs in the opening round.

The four-time NBA champion and MVP missed 27 games last season due to injury and averaged the fewest minutes per game (33.4) of his illustrious career.

James averaged 25.0 points, 7.7 rebounds and 7.8 assists per game last term, while his field-goal (51.3) and three-point (36.5) percentages were his best since 2017-18.

Gearing up for another run, James insisted he is feeling great, having overcome injuries in his quest for a fifth championship ring.

"I still have a burning desire inside of me to want to continue win, hopefully I can bring some trophies at the end of the season," James told ESPN, with the season due to get underway next month.

"That's always been my goal. I love the process more than anything. Hopefully I can put myself in a position where I can do that at the end of the season.

He added: "I'm just a guy who is very determined, who is willing to do whatever it takes for his body to be in the best shape possible to dominate at a high level.

"I'm not afraid to get uncomfortable with anything to get in the best possible shape I can be in."

The Lakers' roster has vastly changed since last season, with Alex Caruso, Dennis Schroder, Andre Drummond, Markieff Morris, Montrezl Harrell, Kentavious Caldwell-Pope and Kyle Kuzma among those to exit.

Los Angeles have added NBA veterans Carmelo Anthony, Trevor Ariza, Dwight Howard and Rajon Rondo along with former MVP Russell Westbrook.

Nine-time All Star Westbrook, who turns 33 in November, led the NBA in assists last season and broke Hall of Famer Oscar Robertson's all-time triple-double record in May.

"Right away he ups our pace," James said. "He's always in the top five as far as pace, being able to get out on the break, able to get some early buckets before the defense is set.

"He's also a flat-out playmaker. A lot of people don’t talk about how unbelievable a passer he is. Everyone sees the rebounds and the scoring but how his passing makes other guys run and better doesn't get talked about a lot. We all look forward dot that as team-mates."

James (35,367) sits third on the NBA's all-time scoring charts, behind Kareem Abdul-Jabbar (38,387) and Karl Malone (36,928) ahead of the new season.

The 17-time All-Star refused to get drawn into the current NBA debate around COVID-19 vaccinations, which has sparked with the likes of Brooklyn Nets point guard Kyrie Irving and Golden State Warriors small forward Andrew Wiggins set to miss home matches due to their refusal to get the vaccine under local state rules.

"I can only speak about myself, everyone has their own choice… I was very sceptical, but after doing my research I felt like it was best suited for myself, my family and my friends," he told reporters on Tuesday. "That's why I decided to do it."
