Perch/Williamson definitely for the first, but don't think Krul could have done much for the second. It was his near post, but Zoggy really hit it hard.
That's completely irrelevant. He was beaten at the near post, his error.
Rubbish, man. The defenders fault for allowing it to get that far. Add the deflection, there weren't many keepers who would get to that (mainly because the defenders wouldn't have allowed N'Zogbia to get that far).
I quite agree that Barton, Perch and Williamson are equally to blame. But Krul should have done better. And sadly it's becoming a bit of a common theme.
