It suits everyone, Diame, Huddlestone and Clucas made an excellent midfield three, Robertson and Odubajo are far more effective when they've got additional defensive cover and Aluko and Hernandez look a far better partnership up front.
Apart from Bruce's utterly ridiculous piling in to some handbags that were nothing to do with him and Robertson's equally ridiculous lashing out when he was already on a yellow, it was a very good all round team performance.
The only issue now, is what we do with Maloney when he returns, we could really do with him for set pieces, but he doesn't have an obvious role in a 3-5-2, unless he replaces Clucas.
