Problem: FC Barcelona:

In 1980, when the stadium was in need of redesign to meet UEFA criteria, the club raised money by offering supporters the opportunity to inscribe their name on the bricks for a small fee. The idea was popular with supporters, and thousands of people paid the fee. Later this became the centre of controversy when media in Madrid picked up reports that one of the stones was inscribed with the name of long-time Real Madrid chairman and Franco supporter Santiago Bernabéu. In preparation for the 1992 Summer Olympics two tiers of seating were installed above the previous roofline. It has a current capacity of 99,354 making it the largest stadium in Europe.

Why did the stadium need to be redesigned in 1980?
