Russell Westbrook declared he was "not good enough" on his Washington Wizards debut despite recording a triple-double in a defeat to the Philadelphia 76ers.
The Wizards went down 113-107 in their first game of the season at Wells Fargo Center, where Philadelphia scored 40 points in the final quarter on Wednesday.
Westbrook registered 21 points in total, providing 15 assists and taking 11 rebounds, becoming the first Wizards player to claim a triple-double on debut and only the sixth in NBA history.
The 2017 MVP's exploits could not prevent Doc Rivers from making a winning start to his reign as 76ers head coach, though, and Westbrook says he expects more from himself.
He frankly stated when asked about his performance: "Not good enough. Honestly, I am kind of disappointed in myself, just some mishaps and plays where I could have been better.
"I don't like to lose. At any point in my career, I love to go out and win the game. I got to be better next game."
Bradley Beal scored a game-high 31 points for the Wizards and Westbrook is expecting big things from his team-mate.
"He is really, really good," nine-time NBA All-Star Westbrook said. "Not just at scoring the basketball but in creating space and getting to his spots.
"As I watch film, once I get on this plane, I will learn and see how I can be able to help him, make the game easier for him as we go along this journey.
"This is the first of many [games], so we got to make sure, I got to make sure I can make the game easier for him along the way."
