MELBOURNE coach Simon Goodwin has declared enough is enough after a series of undisciplined acts that have cost his team in recent weeks.

Goodwin said suspended forward Tom Bugg would need to win back the trust of the playing group and coaches during his six-week suspension for punching Sydney Swans defender Callum Mills

The coach said his team was a disciplined group, but he was clear that a lack of control both on and off the field in recent weeks would not be tolerated. 

"We've had some undisciplined acts which have cost the team," Goodwin said.

He said the actions were not consistent with the behaviours the club wanted to display. 

"We have to get those acts out of the footy club," Goodwin said.

Apart from Bugg's suspension, four VFL players were declared unavailable for selection in the senior team last week after breaching the club's alcohol policy following Casey's win over Box Hill. 

Clayton Oliver was involved in a social media exchange with former test cricketer Damien Martyn while Bugg himself sent a message on Instagram to his friend Jason Johannisen ahead of the clash against the Western Bulldogs. 

Many people inside Melbourne were uncomfortable with Bugg sending such a public message to an opponent so close to a game, however most pundits applauded it as a bit of fun. 

"[We were] concerned around the team first elements within that, which culminated on Friday night (and the loss to Sydney)," Goodwin said. 

"[This period is] a lesson for our playing group about what we want to stand for and what we want to pursue and the behaviours that lay within that." 

Goodwin said Bugg was developing a plan on how he wanted to manage his six weeks on the sidelines. 

"Tom has got to earn a lot of trust back with the playing group and the coaches. He's got some work to do.  We understand that," Goodwin said. 

"He's going away at the moment to come up with a plan as to how he is going to go about it, and we will continue to work with him and develop him to build that trust again."
