Bundesliga champions Bayern Munich reduced the gap to leaders Bayer Leverkusen thanks to a 1-0 win in the postponed game against Union Berlin on Wednesday.
Bayern were trailing Leverkusen by seven points after a shocking defeat to Werder Bremen at the weekend, but with the victory against Union, they now sit four points behind the league leaders.
The Bavarians found the breakthrough in the 46th minute thanks to Raphaël Guerreiro and had a goal ruled out 10 minutes later because Harry Kane was offside.
There was some tension in 74th minute as Leroy Sané had an altercation with Union coach Nenad Bjelica on the sidelines.
Bjelica shielded the ball away from Sané, who was trying to take a throw in. When Sané tried to retrieve the ball, Bjelica hit him in the face and both had to be separated by other players and the sideline staff.
Bjelica was sent off and on his way out, had heated discussions with the Bayern fans in the stands.
Union, who this season played the Champions League but were eliminated in the group stage, are in a complicated situation in the Bundesliga. They are 15th and just three points ahead of Mainz, the first team in the drop zone.
Earlier this season, Union had a run of 10 winless league games, which included nine defeats.
The match between Bayern and Union was originally to take place last December, but had to be postponed due to safety risks and the travel conditions following heavy snowfall in Munich.
