Borussia Dortmund's grip on second in the Bundesliga has loosened slightly after they suffered a surprise 2-0 defeat at home to struggling Mainz, who took a huge step towards safety.
Dortmund had seen Bayern Munich clinch an eighth successive Bundesliga crown on Tuesday, and perhaps the disappointment combined with the realisation of their title hopes being over was to blame for a lacklustre performance at Signal Iduna Park.
For all of their monopolisation of the ball, Dortmund struggled to supply Erling Haaland with adequate service and Mainz took a shock lead into the break thanks to Jonathan Burkardt's header at the end of a slick counter.
