Bucks center Andrew Bogut wasn't happy with his team's performance against the Celtics on Tuesday night.

Boston pulled away late in the fourth quarter to defeat Milwaukee 98-89 at TD Banknorth Garden.

Bogut starred, posting 25 points, 14 rebounds and five assists, but didn't leave himself out of his rant either.

"We need to play better," he said following the loss.

"I think we just need to step up our energy. I think we're focusing a little too much on offense," Bogut said. "I think we need to just all step up ?- everyone of us, including myself. For us to be a good team, we're not going to be the Warriors or the Suns where we're going to score 120. We need to keep persisting."

After Tuesday's loss the Bucks are 9-11, having lost eight of their last nine games.

Milwaukee coach Scott Skiles said that the team needs to improve defensively following their strong efforts on that end of the floor in early November.
