4. Manchester United 8-2 Arsenal
From scoring seven to conceding eight. This was a nightmare day for Arsenal Football Club.
They went to Old Trafford, home of their fierce rivals and they got absolutely battered. Yes you could say it was a weakened Arsenal team, but nevertheless, they were battered and torn apart by Manchester United.
An Ashley Young brace and a Wayne Rooney hat-trick tore The Gunners apart.
United fans will always have this day over Arsenal fans.
