Six-star Bayern

Bundesliga leaders Bayern Munich demolished Augsburg 6-0 with forward Robert Lewandowski scoring a hattrick to protect their 13-point advantage over second-placed RB Leipzig who beat bottom club Darmstadt 98 4-0 on Saturday.

The Bavarians, who face Real Madrid in the Champions League last eight this month, remained firmly on track for a record-extending fifth consecutive Bundesliga crown with yet another dominant performance.

Lewandowski, who joined Borussia Dortmund's Pierre-Emerick Aubameyang at the top of the scorers' list with 24, beautifully controlled a Thiago Alcantara pass with his right foot and turned to shoot Bayern ahead after 17 minutes.

Thomas Mueller, who earlier hit the woodwork twice, put the ball over the line with his knee in the 36th and Poland forward Lewandowski slotted in 10 minutes after the restart to kill off the game.

Thiago grabbed a deserved goal to make it 4-0 before Lewandowski completed his hat-trick and Mueller earned his second goal to lift Bayern to 65 points.

Leipzig are second on 52 after their win, Naby Keita scoring twice against Darmstadt who collapsed following the sending-off of Sandro Sirigu in the 72nd minute.

Dortmund failed to keep pace, stumbling to a 1-1 draw at Schalke 04 in the Ruhr valley derby to drop to fourth on 47.

Aubameyang put the visitors Dortmund ahead with his 24th goal of the season but Schalke fought back, 20-year-old Thilo Kehrer rescuing a point with a powerful low shot in the 77th minute.

Schalke demanded a penalty for a hand ball in stoppage time and the team mascot caused a furore after the final whistle, racing to the referee to show him a red card over his refusal to award the spot-kick.

Werder Bremen continued their climb up the table, crushing hosts Freiburg 5-2 with a hattrick from Dane Thomas Delaney and their fifth win in six league games lifted them to 11th on 32 points.
