I agree with this although we don't necessarily need to go 442, but I would get Wilson in possibly playing that more advanced midfield role, he'd naturally play closer to Sam and he's capable of drifting wide and allowing Mcginn/Hedges to come more central. He also offers a different type of threat.
I said it on Sunday we must be so easy to defend against, it's such a structured way of playing and we're really relying on something just falling for us. Especially when the build up play was so slow, Dundee must have been laughing.
