Whats the best rival/derby football game in world football?

I agree with Shane, the Dortmund vs Schalke Derby is always good, so is the North London Derby

Are derby games ever fluid or good games?

Rangers vs Celtic (in the past obviously)

Sunderland vs Newcastle

EDIT:

No I am saying they are good derby games – which is a different thing.

To really enjoy/suffer a derby game you have to be in the stadium.

Did you really enjoy yesterday's game? Arsenal scored, closed down the game and Spurs were unable to break through their defence.

Liverpool v Utd, Utd v Chelsea, Bayern v Dortmund are rivalries (some of them reasonably modern) not derbies, they should be more entertaining, because they are between teams of reasonably similar depth of skill.

There's hundreds! Personally for me the best one in England is Sunderland v Newcastle. (Yes not always the best quality) However, Best fans here and no glory hunters up here! Unreal atmosphere.

Around the world they are also many fantastic derbies!

Celtic v Rangers

Boca Juniors v River Plate

Galatasaray v Fenerbahce

Olympiakos v Panathinaikos

Dinamo Zagreb v Hajduk Split

Partizan v Red Star Belgrade

Arsenal Vs Tottenham. Anyone can win in the game.

Yeah i support you in this sense EL classico is getting boring day by day and season by season with predictable results and other stuffs.I would prefer watching EPL over any other leagues then bundesliga than watching boring la liga games

When it comes to rivalry or derby... i like Manchester derby most and yeah manchester united vs liverpool has some different taste all linked with history.

At present we have to rely on cup games for the world's greatest derby, Celtic v Rangers. Outside of that, I think the greatest rivalry would be Boca Juniors v River Plate in Argentina

BVB vs S04 without a shadow of a doubt. They have goals in this game, full on pressure from the start. Great derby to watch.

i agree Arsenal v Tottenham then the Roma v Lazio and Galatasaray v Fenerbahce

Cardiff vs Swansea, watch that this season. They put up a great atmosphere and there will be a few arrests and players fighting.

The best match to watch is only "THE EL CLASICO",,Real Madrid CF vs FC Barcelona..That game is superb to watch for...
