I want to know the answer to the following question:
How long was Nunez president of Barcelona?
All the background I'm provided with is that "His presidency was to last for 22 years, and it deeply affected the image of Barcelona, as Núñez held to a strict policy regarding wages and discipline, letting go of such players as Maradona, Romário and Ronaldo rather than meeting their demands.". Is that enough to answer the question?
