DeMar DeRozan insisted the Chicago Bulls "want to win now" after opening the season 4-0 for the first time since 1996-97.
The red-hot Bulls preserved their perfect record with a 111-108 victory against the Toronto Raptors in the NBA on Monday.
Chicago – the last remaining unbeaten team in the Eastern Conference – were busy in the offseason, having recruited four-time All-Star DeRozan, former second pick Lonzo Ball and 2020 NBA champion Alex Caruso.
It came after the Bulls traded for two-time All-Star Nikola Vucevic last season.
The last time the Bulls opened with a 4-0 record, Hall of Famer and six-time champion Michael Jordan was on the team in Chicago.
"Part of the reason why I even chose to come to Chicago was everyone was eager to be successful, to want to win," DeRozan said after scoring 26 points against his former team.
"Everybody had that chip on their shoulder, from the city to the organisation to the players that I spoke to.
"That was everybody's mindset, it's all about winning now. We're not in a development stage, we want to win now."
DeRozan added: "We've got a long way to go. We've got a lot more to clean up, to learn. It's a long season, man. [The 4-0 start] is great, but we've got a lot more basketball to go.
"We can't carry this record like it's some kind of badge of honour; we've got to understand that the next game is going to be even harder."
The previous two times the Bulls started 4-0 (1995-96 and 1996-97), they went on to win the NBA championship.
"I think we have a lot of high-character guys, we all want to win and we want to win together," Ball added. "I think when you have a bunch of guys on the same team with the same common goal and the same mindset it makes it easier for the chemistry to click. That's what's going on."
