Fa cup sheffield wednesday vs manchester city today at 845pm

I'm afraid that's not correct. The FA Cup is a real competition, but the match you're referring to doesn't exist.

Sheffield Wednesday and Manchester City are both professional football clubs that compete in the English football league system, but they have not been scheduled to play each other in the FA Cup today at 8:45pm.
