Do you not think he would have shown his original form if he'd have been given an extended run in the team ?
That would be a big risk considering how much of a liability he looked in the 7-8 games he played for us this season. It would mean dropping one of our form players, Bellerin, for one of our poorest performers, Debuchy, and hoping he rediscovered his form very, very quickly without costing us points.
