Champions Bayern Munich eased past Schalke 04 2-0 to make sure of top spot going into the World Cup break as they hunt a record-extending 11th straight Bundesliga crown.
The Bavarians, who fielded a starting line-up consisting entirely of World Cup-bound players, scored once in either half with Serge Gnabry and Eric Maxim Choupo-Moting, and with Germany international Jamal Musiala delivering both assists.
Bayern's sixth consecutive league win - and 10th across all competitions - lifted them to 34 points, six ahead of second-placed RB Leipzig, 2-1 winners at Werder Bremen. Freiburg and Union Berlin, both on 27, face each other on Sunday.
Bayern had the upper hand from the start but it was not until Musiala, who at 19 is the youngest Bayern player to reach 100 matches, combined well with Germany team mate Serge Gnabry for the lead in the 38th minute.
"Jamal has played an outstanding first half of the season and will hopefully play even better at the World Cup and the second half of the season," coach Julian Naglesmann said of his attacking midfielder.
"He listens well and he wants to develop. He just has a lot of talent. He also has improved defensively," he said.
The teenager, who also has nine league goals, delivered his sixth assist of the season for Cameroon forward Choupo-Moting, who had earlier come close with a glancing header, to tap in seven minutes after the restart and leave Schalke in last place following their eighth loss in the last nine matches.
The 33-year-old forward is himself in fine form going into the World Cup with 11 goals in all competitions, including six in the league.

Napoli's nervy 3-2 win over Udinese on highlights how the Serie A leaders cannot take their position for granted, coach Luciano Spalletti said.
Spalletti's side almost squandered the chance of setting a club record of 11 consecutive Serie A victories within a season.
Victor Osimhen netted his seventh goal in six league matches to give his team the lead after 15 minutes before Piotr Zielinski made it two before half-time.
Eljif Elmas extended the hosts' advantage after the restart, but Ilija Nestorovski and Lazar Samardzic scored to set up a nervy finale.
"Every victory is a struggle, and the final 15 minutes of this game help to underline just how much these players have achieved so far is not to be taken for granted," Spalletti told DAZN.
"We thought the game was over and took our foot off the gas, but the game is never over because when you can introduce players off the bench like Nestorovski, they can find a way through if you don't keep the tempo up."
Festy Ebosele was an unused substitute for Udinese.
Napoli go into the World Cup break top of the Serie A standings, with their next game to come in early January, with reigning champions AC Milan hoping to close the eight points if they beat Fiorentina on Sunday.
