Bundesliga leaders Bayern Munich slumped to a 3-1 away defeat at Mainz on Saturday handing Borussia Dortmund the chance to take top spot.
Dortmund host Eintracht Frankfurt later in the day and can go one point clear with a win, with five league matches remaining this season.
Trailing 1-0 at half-time, thanks to Sadio Mane’s first goal since October, Mainz then hit back scoring three goals through Ludovic Ajorque, Leandro Barreiro and Aaron Martin.
