Ben Wallace officially joined the Chicago Bulls on Thursday in a deal worth a reported $60 million, saying he hoped to inspire his new team.

"This is a great opportunity to show the young guys that if you take care of business on the floor, do your job, good things happen," the former Detroit Piston superstar told reporters in his first news conference as a Bull at the United Center in Chicago.

He said he would bring energy and intensity to the game that should help pump up less experienced team mates.

Wallace left the Central Division rival Detroit squad earlier this month for a four-year-deal.

Wallace, 31, was key to Detroit's 2004 NBA championship and led the Pistons to the finals in 2003 and 2005.
