All derbies are important. That much is clear. Whether it be Arsenal vs Chelsea, Man Utd vs Liverpool, Inter vs AC Milan and especially Barcelona vs Real Madrid, they are all at the pinnacle of the footballing calendar. However on the 30th of April, a different type of derby will take place. One that will not only put the rivalry into play but also the fate of the entire championship. If Man City win, then try will have won it, if Man Utd win they will have won it. It's as simple as that, and it is very rare for the season to bring up such a situation.
You could call it the final of the Premier League it's that important. It's one of those games you'll be able to look back on and say that exactly where the title was won, as both teams were neck and neck coming into it. While you could argue that on form alone, Man City deserve to win (let's face it, Man Utd have played terribly at times yet they're still somehow in this position), all that really matters in football are the points on the board, and Man Utd, you can't deny it, have done what they always do and delivered in that area.
Moving on to my predictions for the game, it's and extremely tough one to call, as this derby always is. While City thrashed United first time round, this is a very different set of circumstances. As much I am hoping for City to win, my brain tells me to go with United. They have more experience at this stage of the season, and Ferguson will simply not let a slip up happen. Also if they draw, United will probably win the title, so unless city win, you can essentially consider it Man Utd's 20th league title.
