Borussia Dortmund prepared for Tuesday's clash against Bayern Munich with a 2-0 win in Wolfsburg on the second weekend of the Bundesliga restart after the coronavirus suspension.
Goals from Raphael Guerreiro and Achraf Hakimi sealed a victory behind closed doors to leave Dortmund one point behind the Bayern leader.
On Tuesday, Dortmund host defending champions Bayern, who would face Eintracht Frankfurt on Saturday.
Dortmund coach Lucien Favre said the lack of noise from fans at the stadium helped him to give instructions.
"I think it's positive that the players can now hear me better at the stadium," said the Swiss coach from Dortmund, whose calls echoed through the empty terraces.
"Usually only my broad players can understand me."
This was the second weekend of the Bundesliga restart, after a two-month hiatus, as the first European league to resume during the pandemic.
A minute of silence was held before the four games in the afternoon to remember the victims of COVID-19, which has so far killed 8,216 lives in Germany.
In Wolfsburg, Portugal striker Guerreiro, who scored twice in Schalke's goal 4-0 last week, opened the scoring on 32 minutes.
Erling Braut Haaland, who has scored 10 goals in nine games since joining Red Bull Salzburg in January, confused his attempt to find a cross, but Guerreiro was on hand to hit home.
Dortmund had a disappointment at the start of the second half when Wolfsburg winger Renato Steffen cut the post.
English winger Jadon Sancho helped seal the victory when he deflected Wolfsburg's defense and then passed a pass to Hakimi, who shot home 12 minutes from time.
In the final minutes, Wolfsburg received a substitute Felix Klaus, sent off for lack of Hakimi.
"We showed right after the start of the match that we wanted to win," added Favre.
Bayer Leverkusen built Werder Bremen on Monday to move up to third place with a 3-1 victory at Borussia Moenchengladbach, who fell to fourth place.
With the terraces of Borussia Park adorned with 13,000 cardboard cutouts from fans at home, Leverkusen's rising star, Kai Havertz, who scored twice in Bremen's 4-1 defeat, scored again twice.
"Kai Havertz played a little better than Bremen," said Leverkusen coach Peter Bosz.
"But it's not about Kai, it was an excellent performance by the team and Kai was part of that."
With seven minutes to go, Havertz, 20, fired for Karim Bellarabi's pass in the area and fired at home.
French striker Marcus Thuram drew for Gladbach just after the break.
Havertz scored a penalty shortly after, when the assistant video referee saw a foul on Bellarabi in the area.
Defender Sven Bender unwittingly sealed the victory when a free-kick hit his shoulder and flew into the net nine minutes from time.
Second-placed Werder Bremen won their first victory in eight league games with a 1-0 win in Freiburg.
Midfielder Leon Bittencourt hit the winner in the 19th minute with a long shot.
In the agonizing stages, Bremen sent defender Philipp Bargfrede to the second yellow card and Freiburg had a goal blocked.
The result leaves Bremen two points in 16th – which leads to a relegation play-off at the end of the season – but six points in 15th, which guarantees safety.
Paderborn are now nine points clear, with seven games remaining after a 1-1 draw at home with Hoffenheim.
On Friday, Hertha Berlin took neighbors Union Berlin 4-0 at the Olympic derby Stadium to take 10th.
