Thomas Tuchel has admitted he did not know Chelsea would have to play in front of a smaller crowd at Stamford Bridge due to sanctions on owner Roman Abramovich.
The Blues host Arsenal in West London on Wednesday night, with the number of fans set to be limited to around 25,000 season-ticket holders only, compared to its capacity of more than 40,000.
And manager Tuchel revealed he was unaware of the ticket situation, calling on fans to 'push a bit more' to make up for the lack of supporters.
