Thomas Muller expects sparks to fly when Bayern Munich play Borussia Dortmund behind closed doors in a top-of-the-table clash on Wednesday (HK time) which could help settle this season's title race.
Muller scored in Bayern's 5-2 home win over Eintracht Frankfurt while second-placed Dortmund stayed four points behind after a 2-0 win at Wolfsburg.
Dortmund's Signal Iduna Park, which will host the crunch clash, would usually be sold out with 82,000 fans creating an electric atmosphere for the showdown.
However, the terraces will remain empty for the visit of Bayern due to the strict hygiene measures the German Bundesliga insists on during the coronavirus pandemic.
"We don't really know how to get into these games without spectators, but I expect us, and myself, to go to our limits anyway," Muller said.
"Of course, we'd like to have the fans there. There's nothing more beautiful than playing these matches.
"But that's our job, and we're going to show that even without spectators we're capable of playing football with passion."
Bayern are chasing an eighth German league title in a row. A win in Dortmund would leave them seven points clear with six games left.
Bayern crushed Dortmund 4-0 when the teams met at the Allianz Arena in November. However, since then Dortmund have signed Norwegian goal-ace Erling Braut Haaland, who has scored 10 goals in as many league games.
