The problem is, if you take the chances Bruno makes out of the equation then I think we look quite predictable. He's usually the one that can find our wingers in behind the defence, or pulls off riskier passes. This is also why he's so wasteful as he tries things, but he tried things because that's his job and you can see that the team is relying on him half of the time to come up with something.
If you look at how we build up without him, it's usually through feeding the wingers and letting them run at the fullbacks. Or from crosses and set pieces. Two things I think are easily nullified by most opposition.
I get why people are frustrated about his wasteful style, when he doesn't produce it looks like he's cost us. But I don't think that would be the case if he was took out of the team, not with our alternatives.
