Excellent piece on De Gea here;

Personally for me there's no doubt that De Gea cost us against Blackburn but like I pointed out earlier in this thread how many points has Reina, Cech & Szczesny cost their teams this season? De Gea isn't alone. Mistakes were always likely to occur with a young keeper in his first season in the Premier League
I was going to tear you a new one for having a go at him for costing you points but then you went on to point out other keepers have, however the last part is completely wrong. It has NOTHING to do with young keeper in his first season. IIRC VDS made howlers last season, I seem to remember a, not quite Reina last night style but a throw his arms simple shot into the corner that he would save 999/1000 but let in that time.
Keepers make mistake, in EVERY game they ever play, some of these will cost you goals, some won't. A goal happens usually when a combination of players make mistakes, a midfielder and a couple defenders, then sometimes the keeper sometimes not, sometimes the keeper make a howler and its all his own mistake, sometimes its a striker who heads it into his own net for no apparent reason.
That is what football is, De Gea will continue to make mistakes, more this year, more next year, more in a decade. VDS made mistakes that cost you points every season, probably 4-5 times a year that cost you points and another half dozen relatively big mistakes that cost you goals, but no points.
Simple fact is that utd should have scored more than they did, and let in less, then one mistake be it from De Gea or a defender, wouldn't have effected the result.
De Gea didn't cost you points against Blackburn directly, if it was 2-0 and he let in a soft goal, it wouldn't have cost you points, he was just one of, pretty much 9 players who cost you the points in that game.
