It does a lot to help it, the tools are on a smartphone to prove Covid status of individuals and enable easy entry to a stadium. Super spreader events are far more likely to happen going forward.

Hopefully the club will learn a bit about this at the Getafe game, given more stewards required for these extra requirements the price is a season ticket will rocket in future years
