English fans attending the Champions League final in Porto between Manchester City and Chelsea will have to fly in and out of the country on the day of the match, the Portuguese government said.
Uefa announced on Thursday that 6,000 fans from each club will be able to attend the final on 29 May.
The final was moved from Turkey because of coronavirus restrictions.
Portugal is on England's green list so players and fans can attend without having to quarantine on their return home. Turkey is on the red list.
Portugal's cabinet affairs minister Mariana Vieira da Silva said a set of rules had been put in place for those fans attending the final.
