Giannis Antetokounmpo scored 46 points as he became the player with the most wins in the Milwaukee Bucks' history on Friday, with the Chicago Bulls beaten 113-97 at United Center.

For Milwaukee coach Doc Rivers, however, the focus is squarely on preparing for the postseason as the Bucks eye their third NBA Championship.

Antetokounmpo surpassed the 40-point mark for the eighth time this season, also adding 16 rebounds and six assists, as the Bucks recorded their fifth straight victory.

The win was the 489th of Antetokounmpo's Bucks career including both regular-season and playoff games, taking the two-time NBA MVP clear of Sidney Moncrief as the winningest player in franchise history.

"Everybody has to be on the same page, and I feel like the last couple of games, we're doing that and that's why our defense has taken a step," Antetokounmpo said after the win. 

"Hopefully, we can keep it up. Right now, it's just about trust. We've just got to trust one another. That's it, win or lose, we have to have the same trust."

For coach Rivers, who has led the team to an 8-7 run since replacing Adrian Griffin in January, all that matters is ensuring Milwaukee are ready for the postseason.

"We're winning games, but for us, it's not about that right now," Rivers said. "Our whole key is getting ready. That's the first thing I told the players. 

"We still have work to do, we're still pushing, we've got to get better. It's nicer to get wins than to lose, but we're not where we want to be yet."

Milwaukee, who sit third in the Eastern Conference with a 40-21 record, are back in action against the 38-20 Los Angeles Clippers on Monday. 

They then embark on a four-game California road stretch on Wednesday, when they face the Golden State Warriors at Chase Center.
