“A question: What defines a league as strong and what classes it as weak? Should a league’s overall strength be measured on the successes of it’s most powerful constituents? Or on the sum total of all parts? If your answer is the former, then based on the 2009/2010 season’s outcome Spain’s La Liga is undoubtedly one of the strongest in world football. If you lean to the latter answer however, then La Liga may be classed as a league in serious structural trouble.” (Just Football)
