Jayson Tatum says he feels like "the best player" in the NBA when he steps out for games after firing the Boston Celtics to a dramatic 122-118 win over the Los Angeles Lakers.

The small forward drained 44 points in a breathtaking performance as the visitors surrendered a 20-point lead before fighting back to force an overtime victory at Crypto.com Arena.

Tatum, a three-time All-Star, is hunting a first NBA championship this term, having won gold with the United States at Tokyo 2020 last year, and has seen his game push him into MVP consideration.

The 24-year-old acknowledged the noise around the accolade and suggested he feels a cut above when he hits his stride.

"I feel like I'm the best player when I step onto the court," he said. "But there are some great players in this league, and I know I've got my work cut out.

"I just try to go one game at a time.We were down 12 with three minutes left, but we found a way. We needed that [after] losing two in a row.

"We haven't been playing the best, individually or as a team, but we've found a way to get back on track. That feels good. It showed the true character of our team."

Victory for the Celtics moved them to 22-7 for the season, furthering their lead atop the Western Conference and strengthening their best-in-show record in the NBA.

They next return to Boston for a seven-game home-stand through the rest of the year, wrapping up 2022 against the Los Angeles Clippers before a new year trip to the Denver Nuggets.
