Manchester United season ticket holders have been told that if they don't buy tickets for their Champions League last 16 second leg with Olympiakos then their seats for their clash with Manchester City will be taken.
Fans have until 8pm tonight to purchase a ticket for the Champions League tie on March 19 or face missing the clash with Manuel Pellegrini's side in the Premier League on March 25.
Back in 2007, Manchester United instituted a policy that forced season ticket holders to buy tickets for home cup games. The Automatic Cup Scheme forces supporters to agree to buy tickets to every home Champions League and FA Cup game as a condition of purchasing Premier League season tickets.
Season tickets holders face a 'one match suspension' if they don't buy tickets for the return leg of their Champions League tie with Olympiakos after their embarrassing 2-0 defeat last night.
By purchasing a season ticket to watch 19 Premier League games at Old Trafford, fans are contractually obligated to buy additional tickets for Champions League and FA Cup fixtures or lose their seat for one home league game.
If their seat is sold for the game, the season ticket holder can apply for a refund at the end of the season.
