After fighting with teammate Robert Lewandowski in training, Kingsley Coman struck again with two goals to help Bayern Munich return to the top of the Bundesliga with a 4-1 win at Fortuna Duesseldorf on Sunday.
Serge Gnabry and Leon Goretzka scored the other goals as Bayern reclaimed its one-point lead from Borussia Dortmund, which scraped a 2-1 win over Mainz on Saturday.
Lewandowski failed to add to his league-leading tally of 21 goals but congratulated Coman for his scores. There was no sign of any animosity between the two following their training-ground punch-up on Thursday.
Duesseldorf, which grabbed a 3-3 draw in Munich earlier in the season, had its Bundesliga survival confirmed on Saturday thanks to relegation-rival Stuttgart's defeat to Bayer Leverkusen and was effectively only playing for pride in its second game against Bayern.
Bayern coach Niko Kovac made no changes from the team that started in the 5-0 rout of Dortmund the weekend before and was rewarded with another concentrated performance from his side.
Coman struck the post early on before Thiago Alcantara headed just wide. Bayern duly made its early pressure count through Coman in the 15th minute, when Thomas Mueller missed his cross before the ball flew inside the post.
Dawid Kownacki went close for Duesseldorf in response, but Coman struck again before the break when Joshua Kimmich pulled the ball back for the French winger to rifle inside the top far corner.
Gnabry effectively ended the game in the 55th after Mueller headed on a corner.
Mats Hummels was penalized for hand ball after referee Felix Zwayer consulted video replays and Dodi Lukebakio claimed Duesseldorf's consolation from the spot in the 89th.
There was still time for Goretzka to score in injury time.
Five games remain for both Bayern and Dortmund.
Hoffenheim defeated Hertha Berlin 2-0 at home earlier to move sixth — the last place for Europa League qualification. It was Hertha's fifth consecutive defeat.
Fourth-place Eintracht Frankfurt was hosting Augsburg later.
