FA Cup Third Round

Taking your shirt off and celebrating when it's offside has got to be really embarrassing.
 
If this is offside I officially have no idea what the rules are anymore. Playing the ball? Behind the ball? Seen it all tonight
 
I have no idea how that’s off nor do I have any idea how their goal was on
 
I don’t get where he is offside there? Even in the first phase of play he was behind the ball
 
That's a worse decision than the one for Liverpool that counted. Unbelievable.
 
Wait, what was the offside, was it the ball going back to the guy who took the corner?

Didn't the ball get played backwards
