Michael Olise (right) has scored nine Bundesliga goals since ing Bayern Munich last summer
Bayern Munich moved one victory away from winning back the Bundesliga title as they beat Mainz at home.
Leroy Sane slotted into the bottom corner from close range to put Vincent Kompany's side in front.
Michael Olise jinked inside and fired a low finish past Robin Zenter in the Mainz goal as Bayern increased their lead before the break.
England international Eric Dier rounded off the victory in the closing stages, heading in Olise's corner.
Bayern would have won the league on Saturday if last season's champions Bayer Leverkusen had dropped points.
However, Xabi Alonso's side were 2-0 winners against Augsburg as the eight-point gap between the two sides remained intact.
Prior to Leverkusen's unexpected success last term, Bayern had won 11 consecutive Bundesliga titles.
Mainz had a chance to reduce their deficit at Allianz Arena when Nadiem Amiri attempted to curl an effort into the top corner, but Jonas Urbig dived to his right to beat it away.
The victory margin could also have been greater. Bayern's Sane bent a strike wide of the far post before sending a delicate chip over the advancing Zentner and against the post, as the home side dominated.
Thomas Muller came on with six minutes remaining to make his 500th Bundesliga appearance, with the Bayern legend departing the club in the summer.
Regardless of Leverkusen's result next weekend, victory for Bayern away at RB Leipzig (Saturday, 14:30 BST) would seal their 33rd Bundesliga title.
