Pope. All the stats suggest he's the next best thing to De Gea in terms of ridiculous saves, and he is by far the strongest at commanding the penalty area in the PL. I'd have him ahead of Allison.
My problem with Pope is that he's had one good season, and Charlton didn't want to play him before that so palmed him off to Cambridge, York, Aldershot, Welling etc before that as they didn't rate him.
