Martyn Ziegler’s article in The Times today sounds promising:
Uefa is confident that Chelsea and Manchester City supporters will be able to attend the Champions League final in Porto via independent travel despite Portuguese authorities saying that all fans would have to take charter flights and remain in a biosecure bubble.
Many supporters have already booked their flights and hotels after Uefa announced yesterday that Porto has been chosen instead of Wembley as the replacement venue for Istanbul — a decision that paves the way for Chelsea’s owner, Roman Abramovich, to attend the match at the Estádio do Dragão.
Each club has been allocated 6,000 tickets for the final on May 29. They are laying on one-day travel packages with charter flights, which would adhere to the bubble plan. But there is still uncertainty over non-official travel, especially as Portugal has extended its “state of calamity” until May 30.
Mariana Vieira da Silva, Portugal’s cabinet affairs minister, said that fans will “come and return on the same day, with a test done, in a bubble situation, on charter flights” and be in Portugal “less than 24 hours”. She said fans who travel without going to the stadium would not be subject to the same restrictions.
Uefa has been in high-level talks with Portuguese ministers and it is confident that there will be clarity after the weekend so that anyone who has booked travel and accommodation independently will still be able to get into the stadium with a valid ticket.
