We're certainly not their foremost concern, but I think there are a lot of things that need consideration to be able to facilitate a move, particularly at this late stage.
I think some people think it's as simple as cancelling a reservation at a restaurant and booking another restaurant for the same night.
Before any move to Wembley can happen, the EFL needs to make alternative arrangements for the play-off final. This can take time as they seek alternative stadia, corporate, broadcasting and advertising arrangements.
If Wembley gets the green light then UEFA, in turn, needs to sort out its own corporate, broadcasting and advertising arrangements. It needs to come up with a new design for how the stadium will be decked out on the day, re-route and redesign its merchandise for the occasion.
UEFA will need to enter dialogue with the Westminster government about quarantine arrangements for the various nationalities that will be coming over to watch/cover the game. This will need to be a detailed breakdown of numbers from respective countries, expected arrival dates, expected departure dates. UEFA need to sort out accommodation and transport for the thousands of people travelling and then diseminate that information.
UEFA then needs to examine its contract with the Turkish FA/government and come to an amicable agreement both in terms of finance and future hosting of the event. UEFA then needs to find the money to compensate Turkey.
The UK government needs to give UEFA indication as to how many tickets it can sell for the event and a pricing structure needs to be agreed. Hosting it at Wembley likely means that FEWER tickets will be sold than if it was hosted at the Ataturk Stadium. UEFA needs to engage both clubs about how many tickets each will receive for the event.
The FA needs to agree with UEFA how much money it will take for the use of Wembley.
The FA needs to sort out its match-day operation and ensure enough staff are available.
The Met Police will need to be informed and arrangements made. The policing will need to take into account the vast number of ticketless fans who would likely turn up (particularly from Chelsea) and how Covid might affect how the event is policed.
Rumour has it that Wembley will allow 22,500 people to attend. In Turkey, they're looking at 25,000. They might argue that more members of the public will be in attendance at the Ataturk than Wembley, albeit not fans from the clubs. At the absolute best, each club might get 4,000 tickets at Wembley, half of which will go to non-fans.
When you examine all of the above, the case for moving it to Wembley for the benefit of a very, very small number of genuine fans is severely weakened. The only reason for it not to take place in Istanbul is Covid-related which, in isolation, is a good enough reason alone until you realise that moving it to Wembley presents exactly the same problem with the numbers of outsiders coming into this country.
This is not an easy problem for the organisers to solve and I think any attempts to keep it in Turkey with special dispensation and strict Covid rules for the travelling parties is understandable.
