I don't think he'll do much of a job v Sydney; their defence is 10x better than the Vuc. I like him, but he's a one trick pony. Hooper would provide more, especially in the opening stages.
If we want to do more this season and evolve as a team, we need to create more chances - we're playing well with not much end result. Davila has been carrying the team on his back at times, which showed v the Victory when he didn't have a great game but still had our best chances (except for DeVere's header off a corner)
