Fans have been warned by the Premier League that fixtures could be moved at "relatively short notice" next season because of the number of teams playing in Europe.
A record nine top-flight clubs have qualified for Uefa competitions in the 2025-26 campaign.
The Premier League said there is an "increased likelihood" that games will be rescheduled if English teams reach the latter stages, and it suggested fans take this into consideration when planning their attendance at games.
Liverpool, Arsenal, Manchester City, Chelsea, Newcastle and Tottenham will be playing in the Champions League next season.
