The Champions League final between Chelsea and Manchester City is likely to be moved from Istanbul to Wembley Stadium if certain concessions and guarantees can be made following a meeting between UEFA and the British government later today.
Last Friday's decision to add Turkey to the travel red list put an end to any hopes of supporters travelling from England for the game, although the government would have made quarantine exemptions for players and staff.
A number of issues need to be discussed today, with UEFA seeking assurances around capacity and the ability for international media rights holders and corporate partners to be given travel exemptions for the game on May 29.
The governing body wants capacity to be set between 20,000 and 25,000 - similar to the number that was planned for Istanbul's Ataturk Stadium. This Saturday's FA Cup final between Chelsea and Leicester City, the government's biggest trial event to date, will see 20,000 in attendance.
That increase would be good news for both Chelsea and City fans, who could get about 4,000 tickets each. The remaining will go to sponsors and UEFA suits, many of them dependent on the government temporarily relaxing quarantine rules.
Should Wembley be confirmed, the Championship play-off final will either be rescheduled or moved to an alternative venue. There is the potential to delay three EFL play-off games by 24 hours but no decision will be made until after confirmation of the Champions League game.
As first reported by the New York Times, Porto is being considered as a seccondary option for the Champions League final. Portugal was last week placed on the green list for travel, which would enable supporters to travel with fewer restrictions.
The Tottenham Hotspur Stadium was never considered - partially because UEFA are determined not to reward one of the clubs behind the Super League breakaway plans.
