LOS ANGELES (AFP) — LeBron James said the Los Angeles Lakers cannot afford to make any mistakes when they face off against Stephen Curry and the Golden State Warriors in their blockbuster playoff series opener on Tuesday.

James and Curry go head-to-head in a playoff series for the first time in five years on Tuesday when the Lakers and the Warriors meet in Game 1 of the Western Conference semifinals in San Francisco.

It is the latest heavyweight showdown between two of the greatest basketball players in history, who faced each other in the National Basketball Association finals for four straight years between 2015-2018.

The 38-year-old James leads a Lakers team who have hit form at the right time after struggling to muscle their way into the playoffs, crushing the Memphis Grizzlies last Friday to complete a 4-2 series sweep.

Curry, meanwhile, produced a 50-point masterpiece on Sunday as the defending NBA champions snatched a 4-3 series win over the Kings in Sacramento.

Talking to reporters on Monday, James spoke of his admiration for Curry as the two friendly adversaries prepare to battle it out once more.

"Nothing but the utmost respect for Steph and all he's been able to accomplish — not only on the floor but off the floor," James said.

"It's great to have people like that in this league setting the example for the generation to come."

James, meanwhile, warned his Lakers teammates that they would need to be "locked in" against a ruthless Warriors team who have shown repeatedly they will punish mistakes.

"They're right there at the top along with those great San Antonio Spurs teams. If you make a mistake, they make you pay," James said.

"It's that simple. So, we have to be locked in," James added, citing the fact that Curry was able to score so freely on Sunday despite being closely marked throughout.

"They're going to do a great job of scoring even when you've got a body on top of them," James said.
