There could be hordes of empty seats on show at Old Trafford for Tuesday's Carabao Cup semi-final between Manchester United and Manchester City.
Scores of tickets remain unsold for the first leg of the clash just 24 hours before the two sides kick off in the crunch encounter.
Tickets remain available in all four stands for United fans to purchase, with supporters so far failing to snap up the large general sale allocation available to fans who don't have season tickets.
The clash will be the first game at Old Trafford in 2020 and fans may have been put off by the prospect of spending more money immediately after Christmas.
Prices for the game in all areas of the ground range from £10 for juniors up to £66 for adults, with the latter cost seemingly putting off supporters.
Attendances at Old Trafford have fallen in recent seasons, with the average turnout at home games down to 74,879 in 2018/19 - the lowest figure since 2009/10.
That figure is likely to drop again at the end of the season, with the highest attendance this season 73,737 for October's clash with Liverpool.
Attendances have plummeted as low as 50,783, which was the number of fans who watched United in action against Astana.
Old Trafford currently has a capacity of 76,000, the highest in the Premier League and - 14,000 more than Tottenham's new stadium, which is the second biggest.
