Is Glasgow the only European city with 3x 50,000+ seated stadiums?

When you think about it, there probably aren't that many cities in the world that have multiple sporting stadia capable of holding more than 50,000 people. For example, I can't think of too many in even a city as large as New York, where both major NFL franchises share the recently built MetLife Stadium (in New Jersey). Indeed, the largest stadia in the States are often orientated to college sports. I think the two largest stadiums in the States belong to the University of Michigan (in the city of Ann Arbor, where the population is only slightly larger than the stadium's 109,000 capacity) and Pennsylvania State University.
