Kyrie Irving has his eyes on the prize after starring for the Brooklyn Nets in a Thursday's 121-109 victory over his former team the Boston Celtics.

Irving put up 40 points in the Nets' first game back since the NBA All-Star break, reminding the Celtics what they have been missing out on since he left in 2019.

His efforts laid the foundations for a 12th win in 13 games for the Nets, who were without Kevin Durant and Blake Griffin as former MVP James Harden posted 22 points and 10 rebounds.

While Irving clearly enjoyed his night's work, he is looking ahead to the playoffs after snapping the Celtics' four-game winning run.

"I'm just waiting for the main stage," he said. "Playing in front of millions of people and it actually mattering in terms of win or lose or go home.

"I'm looking forward to that, but games like this in the middle of the season against guys that you know well, that's always a blessing."

Irving hugged his old team-mates at the end of the contest, apparently making a mockery of the notion he has a frosty relationship with his erstwhile colleagues.

"Big surprise to a lot of people," he joked. "All that s*** talking about me and all the relationships I have with every former team-mate of mine."

Harden was full of praise for Irving, suggesting it was the 28-year-old's mental toughness that elevated him above the crowd.

"He's a different breed," Harden said. "He has that killer mentality in a sense of, no matter who we play or where we're playing, he is going to go out there and try to destroy the opponent, and that's something that you'd want on your team at all times.

"That mentality is what sets him apart from a lot of guys in this league."
