Mainz stuns Bayern to put title party on hold
Bayern Munich came looking for a title party and was served with a cold dose of reality as survival scrapper Mainz earned a stunning 2-1 win over the Bundesliga leader.
First-half goals from Jonathan Burkardt and Robin Quaison put in-form Mainz in charge, and a leggy Bayern side, which would have been crowned champion with a victory, lacked the zip in its game to overturn the deficit.
Manuel Neuer was at fault for the opener, but also produced some big saves to keep Bayern in touch with its impressive host, which has been the most-improved team in the league in the second half of the season.
When Quaison headed the second, he showed the aerial threat that was rarely seen from Bayern's fit-again talisman Robert Lewandowski in this game. Lewandowski snatched a last-gasp consolation after a defensive clanger, but it came too late to be significant.
Burkardt stunned Bayern in the third minute when he was left unattended on the edge of the penalty area and fired a thumping shot that Neuer could only help into the left corner.
Bayern had Lewandowski back in its ranks after a knee injury absence, but before the Polish striker could show any threat it was almost two goals behind, Neuer producing a fine save at full stretch to touch a 20-yard header from Danny Latza against the left post.
Lewandowski fired waywardly from his first chance before Neuer again prevented Bayern slipping two goals behind, Quaison turning Jerome Boateng far too easily and hitting the target with a thumping shot that bounced away off the well-placed goalkeeper.
Bo Svensson's Mainz side, having won four and drawn two of its previous six games to surge out of the relegation zone, doubled its lead in the 37th minute when Quaison headed past Neuer after Philipp Mwene's free-kick from the left proved a perfect, teasing delivery.
Hansi Flick's reaction was to bring on three substitutes at the start of the second half, hauling off Leon Goretzka, who was perhaps fortunate to avoid a first-half red card, plus Kingsley Coman and Leroy Sane, and introducing Eric Maxim Choupo-Moting, Jamal Musiala and Tanguy Nianzou.
A stray arm from Lewandowski caught Mainz midfielder Leandro Barreiro in the face, drawing blood, but it appeared accidental. It was nevertheless not the impact Bayern was looking for from its star striker.
Bayern trailed 2-0 in the first meeting of these sides this season but recovered to win 5-2; however, until Lewandowski's stoppage-time strike, its second-half goal threat in this game was limited to half-chances that the likes of Choupo-Moting and Joshua Kimmich could not convert.
