Senegal's clash with Netherlands (0:2) took place at Al Thumama Stadium and was watched by 41,721 fans, 1,721 more than its official capacity. USA and Wales (1:1) played at Ahmad Bin Ali Stadium with an attendance of 43,418. The venue officially has a capacity of 40,000 spectators. How did this happen? The answer is very simple. As we know, the big football organisations at the tournaments they organise used to reduce the actual capacity of the arenas due to their restrictive approach to security.
