Pressure is increasing on UEFA to allow away supporters to attend fixtures in club competitions this season by removing the blanket ban.
Manchester United and Ajax have urged the governing body to reconsider, after travelling fans were not able to watch games in the qualifying stages of the Champions League, Europa League and the Europa Conference League.
Sportsmail understands that a decision is yet to be made on whether they will be permitted at fixtures starting from next month, but calls for the ban to finally be dropped are continuing to grow.
