Los Angeles Galaxy coach and General Manager Bruce Arena says the team regrets the exchange between David Beckham and a fan at halftime of its exhibition against AC Milan.

Arena’s comments Monday come a day after Beckham was the target of frequent booing and derisive banners held up by one of the team’s support groups during Beckham’s first home game since returning from a five-month loan to AC Milan.

At halftime of Sunday’s 2-2 tie, Beckham walked toward the L. A. Riot Squad section and motioned to a fan to come closer. The man jumped down from the seats and was arrested by police for trespassing.

Arena said in a statement issued by the team that it’s important for fans to be able to voice their opinions but they must do it in an appropriate manner.
