Arsenal Women have been forced to move their high-profile Champions League game against Bayern Munich next month away from Emirates Stadium because of a scheduling clash with the men's team.
The game has been set for Wednesday, 18 December, with the club selling tickets since September.
However, it now clashes with the EFL Cup quarter-final between the men's side and Crystal Palace.
The only midweek day available to Palace, if they are to get two rest days between fixtures, is the Wednesday as they have televised Premier League matches on the previous Sunday and the following Saturday.
