Uefa is set to decide by Wednesday whether to switch the Champions League final to Wembley from Istanbul because of travel restrictions.
Chelsea face Manchester City in the final on 29 May.
But fans have been told not to travel after Turkey was put on England's travel red list.
There is a fixture issue to resolve, as Wembley is scheduled to stage the Championship play-off final on 29 May. However, it is understood the EFL would consider moving the match if asked by Uefa, and its board would make the final call.
UK citizens returning from red list countries are required to quarantine at a government-approved hotel for 10 days.
