The deflection is 100% in line with Sigurdsson's head.Answer me this then, how can a player sitting on the floor block the view of a 6'4" keeper? OK he is bent down a bit, but the camera angles conclusively showed there was no way he was blocking his view. Yes, he was in his eyesight, but that doesn't make it an offence.
De Gea dives as the shot came in and had full sight of the ball. Once Maguire deflects the shot there is not a keeper in the World that could have saved it once they had gone the wrong way, and Sigurdsson's position played no part in him not being able to save the shot. I can see the part of the offside law that people might say means it could be disallowed, as below, but the bit in bold simply is not met in this case.
making an obvious action which clearly impacts on the ability of an opponent to play the ball
There's a definite action, but it is impossible that this action impacted De Gea's ability to play the ball.
To me there is not a full sight line, because of the offside player, thus he is involved in play.
I've just performed a very basic science experiment at work. I am 185cm, roughly the same size as Sigurdsson(186). When sat on the floor I am 1.05m high. A football goal is 2.44m (8ft) high, De Gea (192cm) is bent down and looks to be just over halfway up the post. That makes him stood at a height of roughly 4.5-5ft.Answer me this then, how can a player sitting on the floor block the view of a 6'4" keeper?

Where is the camera angle that shows that he is in no way blocking the view?
