I thought Henderson could've done better with Newcastle's first goal, though he's obviously not at fault, it was a total defensive howler, but he gets something on it, on another day he probably saves it. Not sure what happens on the 2nd goal though, he doesn't look ready, and doesn't even move, though the defender does just keep backing off and backing off, perhaps his view was blocked. No chance on the third.
None were his fault, but I'd probably be a bit miffed if De Gea had conceded that first goal considering how much he got on it.
