I want to know the answer to the following question:
On which date did FIFA request that all European leagues reduce the number of teams within themselves to 18?
All the background I'm provided with is that "On 8 June 2006, FIFA requested that all major European leagues, including Italy's Serie A and Spain's La Liga be reduced to 18 teams by the start of the 2007–08 season.". Is that enough to answer the question?
Answer: yes
