I thought he struggled today against a decent full back, but the sign of a good player.........etc,etc
You could say he struggled against a good full back, but I don't think that was the case.
Southampton were so deep and so compact there was literally no where for him to run.
On the one occasion they left any space in the first half he exploited it and should have scored/got a pen.
His presence alone was likely the reason Southampton were so deep and allowed us to be so dominant and strong defensively.
