Murphy’s law is Carlton must speak up on field

AFL: Actions may speak louder than words, but it's a lack of voices on the field that may be partly to blame for Carlton's disastrous 0-4 start to the 2014 season.

It seems everybody has had their say about what's going wrong in the Blues camp, with football manager Andrew McKay suggesting leadership was an issue, defender Andrew Walker admitting the players could "go quiet" during games, and captain Marc Murphy (pictured) saying his players were trying to have "more voice" on the field.

"We're not the loudest group, but I think we've taken steps forward," Murphy told reporters yesterday.

In his second season as captain, Murphy defended his own leadership and said coach Mick Malthouse had the team's full support.

"I think I've got the respect of all the boys and the club as a whole … that's all that matters to me," he said.

Carlton plays the Western Bulldogs at Etihad Stadium on Saturday.
