Same here. I think they will only resort to hoof-ball if they are taking a beating, and Merts in that situation would be a better bet. As a starter, and at home I would go with Gabs. This is the benefit of having more than two good players in defence, means we can chop and change to suit who we are playing. More speed and aggression for Rooney, Martial, as you say is a must. But as we know Wenger dont set up a team to face a certain opponent, he will start with Merts!
