I agree 100%, I am by no means Maguire's biggest fan but I think the people blaming him for the third goal are missing two key points, possession and time.
Fact is, we were 2-0 down with not long to go so I genuinely think Maguire assumed De Gea would be aware of this (although that's possibly an error to assume that) as 99.99% of goalkeepers would be in that situation.
Surely letting the ball roll back to your keeper and us retaining possession is a better option in that situation than Maguire giving possession away by aimlessly hoofing it clear or out for a corner.
I would blame Maguire if the ball had been fired across the box at pace and he just left it but the fact is, the deflection took all the sting out of it and it was the goalkeepers ball all day long in my opinion.
The most worrying thing is that this is not a one off, this happens pretty much every time a cross comes near De Gea, he may as well not be there.
Ive been saying this for years now but I'm genuinely baffled as to how our coaching staff (who are paid to analyse these things) cannot see how much of a problem this.
