Thomas Mueller and Thiago Alcantara scored twice to help ruthless Bayern Munich romp past Werder Bremen 5-0 on Saturday and increase their lead at the top of the Bundesliga to eight points. Borussia Dortmund, who held the champions to a goalless stalemate last weekend, can cut the gap back to five at home to Mainz on Sunday but are running out of games as Bayern hone in on a fourth straight title and third under departing coach Pep Guardiola. New Eintracht Frankfurt coach Nico Kovac earlier suffered a debut to forget with a 3-0 loss at fourth-placed Borussia Moenchengladbach sucking the Bundesliga strugglers further into a relegation dogfight. Second bottom Hoffenheim boosted their hopes of avoiding the drop with a 1-0 win over VfL Wolfsburg which puts them level on points with Eintracht, who occupy the relegation play-off spot with eight games left. Bottom side Hanover look doomed however after their 2-0 home defeat by Cologne while Augsburg came from 2-0 down to draw 2-2 at fellow strugglers Darmstadt. VfB Stuttgart also fought back to draw 3-3 at fellow midtable team Ingolstadt. Bayern coach Guardiola rested Arturo Vidal, Douglas Costa and Arjen Robben for the home late game with one eye on Wednesday's Champions League last 16 second leg against Juventus, handing a first appearance since October to Mario Goetze.
