You might be able to see it but it's simply not going to happen. It's just another in a very long line of Internet theories that never ever actually happen in reality. Imagine the two clubs were reversed, would you as a city fan wanting the owners out go down to old Trafford on a champions league semi final game to try and make some kind of point? Or a more likely scenario, would you or any blue you know be prepared to go down to the next old Trafford protest undercover to cause trouble and have it reflect poorly on united? It's sheer lunacy. I really don't get what world some people live in where they think this is something that's going to happen.
