On the last point, I agree. And you'd have the safety blanket of being able to start Robinson off behind him but with the ability to push up beside him if necessary.
Interesting you fancy McGrath over Knight. I don't know where I sit on it at the moment. I think Hendrick adds a little guile beside Cullen but if Hendrick were missing I'd like to see Knight beside him. Failing that, I would like to see Knight start elsewhere but I see your logic on McGrath beside Robinson definitely. I suppose Knight over McGrath might work better against a better side with midfielders that could/would dominate us e.g. Portugal.
I wish Kenny had started McGrath over Horgan on Saturday to give a better indication of what that front three would have looked like. I said it before the match that he really should have. And at half time it was obvious that he really, really should have.
