I've played in this fixture myself and the minimum expected by supporters of any United player in a game like this is a high level of aggression and tenacity - getting up to the ball, and being hard to beat.
Sometimes, it is just about running around. That might sound like a throwaway comment but if you can do that early on to get the fans behind you and combine that with a good tactical plan, it carries you a long way.
There comments you'd expect at a lower standard of football not the fucking Premier League!! Running around should be the bare minimum.
As for a tactical plan.......... he's fucking deluded, huff and puff was all it was from both sides, hardly any quality at all and i honestly thought neither side had any idea what to do.
