I want to know the answer to the following question:
Barcelona ranked first in the IFFHS Club World Ranking in what years?
All the background I'm provided with is that "Barcelona was ranked first in the IFFHS Club World Ranking for 1997, 2009, 2011, 2012 and 2015 and currently occupies the second position on the UEFA club rankings.". Is that enough to answer the question?
Answer: yes
