Yeah well we're playing very well, in the first final of the season, pretty safe in top 4 and a couple of games from actually challenging for the title, going well in the FA Cup and just have Barcelona to overcome for a good Europa League run, 13 OT wins on the bounce. De Gea has played a big part in that success.
You'd have to be some really miserable fecker to still have something to whine about. You could argue that Casemiro is one of the worst players to have in your team with the amount of suspensions he's picked up. How many points could he have cost us compared to De Gea? You can throw your dumb statistics around as much as you like.
