Porto caught United off guard with their flying start and might have had the entire tie wrapped up if they had taken their chances and not gifted WayneRooney an equaliser.
United could have enjoyed a more comfortable victory had WayneRooneynot fired his penalty high and wide of the Arsenal goal, after the Gunners full-back Gael Clichy was deemed to have illegally handled.
Wayne Rooney's winner might not even have been his fault because he got dragged somewhere else, but if I see a winger get a cross in I will ask what more the full-back could have done to stop that happening.
But there's no doubt that even on a poor night - and I'm not saying he had a poor night against Liechtenstein - WayneRooney does things that put you on the edge of your seat.
For instance, the latest information on whether WayneRooney, an injured English striker, will or will not be fit to play, may move the England share price.
With the snow still teeming down in the second half Tottenham cranked up the pressure, though they were fortunate not to concede a penalty when Steven Caulker looked to have tripped substitute WayneRooney inside the area.
