Clubs could be disqualified from European competition next season if national governments impose travel restrictions that impact the staging of a tie across the continent.
The coronavirus crisis has forced many countries - including the UK, most recently with Spain - to impose travel restrictions, with anyone returning to the UK from such a country forced to self-isolate for 14 days.
In light of the ever-changing situation, UEFA have published a number of new protocols regarding competition for next season, including the potential forfeiting of games and expulsion of teams if certain stipulations cannot be fulfilled.
