Most popular soccer league?

Does anyone know whats the most popular soccer league in Europe? There's all these different soccer leagues such as the EPL, Champions League, Uefa cup etc. But I just want to know which league people tend to follow the most.

The big three leagues are:

England

Spain

Italy

But quite a few people also follow dutch, french, portuguese, greek, turkish, scottish etc etc..

UEFA Cup and UEFA champions league are widely followed by most of europe... which hopefully i will see my beloved Celtic in either of next season :P

English Premier League has the most exciting football. Foreign matches often seem a bit dull to me.

English Premier League (The Premiership) is far and way the most popular.

Premier League is the most popular one nowadays. A few years ago it was La Liga.

Barclays Premier League, obviously. I will add the Champions League as we have the best teams qualifying for it.

The BPL and Serie A come to mind.

I say Italy is the most popular soccer league.

Best football league is probably the English Premiership. La Liga is lacking, but it's the most popular.
