Bollocks! I'm not surprised if the one who write the article or doing the research is the fan of any of those club wearing red shirt. Charlton or Barnsley perhaps?
Ok, the original article is here and if you are one of those red supporters, I congratulate you! But, the fact is this research may only valid to the English Premier clubs and also not all of those who wear the red shirts are more successful than any other team who is not.
My personal opinion, one sided and from a fan of the team who's wearing the black and white stripes, that article is very biased and ridiculous, it's just so stupid to publish such one side opinion and unreasonable perception.
