I reckon De Gea might have saved it if Sigurdsson's not there. If he sees the deflection he has enough time to react to it.
He should have gone with one hand. Too many keepers now think about making the perfect save and pushing it out of danger instead of just keeping it out of the net.
He wouldn't have but it's pointless.
The player on the ground was;
Offside
Clearly in the keepers view
Had to pull his legs out of the way to not touch the ball therefore clearly interfering with play
Why was he sat on the deck for so long anyway, had ample time to get up.
