Real Madrid have reportedly missed on €15million (£13m) of revenue by having their matches against Liverpool and Barcelona behind closed doors despite reduced expenses.
Zinedine Zidane's men beat the Reds 3-1 in midweek at the empty Estadio Alfredo di Stefano - which Jurgen Klopp criticised - and now have one foot in the Champions League semi-finals.
And now the Spanish giants face the prospect of El Clasico on Saturday without their passionate fans - as well as a significant hit to their finances, according to MARCA.
Work is currently being undertaken on the Bernabeu while games take place behind closed doors and it is hoped that modernisation will take place in time for the 2022-23 season, with the team due to move back to their iconic home next season.
