Manchester United fans are set to be barred from attending their opening Champions League fixture away to Young Boys because of Covid-19 regulations.
The match at the Stade de Suisse in Bern takes place next Tuesday and could see Cristiano Ronaldo play the first action of his second spell with the club.
On Monday, UEFA announced that travelling supporters would be able to attend European fixtures but only if the home team's city health and government Covid rules permitted them to do so.
But as things stand, Young Boys are insisting that all fans show a Switzerland or EU Covid Vaccination Certificate to enter the stadium in accordance with local rules.
