It just shows the fickleness of fans. I'm sure Barca will be higher the Real now after winning the Champions League.
Having worked around Knowsley in places such as St Helens, Whiston where its very much the dividing line between Liverpool and Manchester I've always noticed many people are either Manchester United, Liverpool or Everton fans. In five years i'd never seen a Man City fan, now you see a couple of shirts each week.
If anyone plays the Premier League fantasy football you can see which fans have the best average support score and how many there are.
At the end of the season about 2 years ago I saw that City had about 30,000 registered fans, we had about 70,000 along with Villa and Newcastle. Spurs had about 100,000 and the four "big clubs" much higher.
Today City has 56,000, Newcastle 54,000, Everton 49,000 and Villa 47,000. Those 26,000 people have just emerged because City have money.
