Went there for the Manchester United v AC Milan in early August. We were in U24. No air, the roof was closed. Very uncomfortable. With no fresh air getting into the stadium it was very uncomfortable, difficult to breathe. Very warm. This stadium s lack of ventilation is an accident waiting to happen as it was nowhere near full. Going down the steps to the bar and toilet area the difference in air quality was really noticeable. I will be looking into which agency I should report .this accident waiting to happen. The air conditioning helped a bit but not much.
