The first game I attended was Manchester United 3 vs 1 Leicester in 1996. It wasn't very memorable, and even if it was I wouldn't remember it. The records say Solskjaer scored and Nicky Butt grabbed two, and I'll take their word for it!
Best Game
The 8-2 against Arsenal. It wasn't exactly end-to-end but it was a masterclass in football and it's always nice putting one (or eight) over your old rivals.
Worst Game
Undoubtedly the Carling Cup against QPR in 2008. United won 1-0 through a Tevez penalty, I don't believe anything else happened.
It's the home of the team I support, nothing beats that.
Easy. The Lily Holmes stadium in Sydney. There's not a lot to say about it frankly.
