Five second-half goals see Bayern Munich return to the top of the Bundesliga table.
A double from Robert Lewandowski and goals to Leroy Sane, Niklas Sule, and Joshua Kimmich saw Munich cruise to a win in their first match of 2021.
Joshua Kimmich returned to Hansi Flick’s starting line up with Leroy Sane given a chance from the outset with the injury to Kingsley Coman.
It took just four minutes for Mainz to show their intent with young attacker Jonathan Burkardt having the match’s first shot on goal, however, Manuel Neuer produced what was a relatively easy save.
The game was open and entertaining with both sides having chances in what was an end-to-end game. Bayern slowly came to grips with the match and controlled possession however with their high line Mainz had numerous chances to go ahead but could not find a way through.
With just 15 minutes gone, a great move started by Corentin Tolisso ended with Serge Gnabry finding the Frenchman however his shot went wide as Bayern looked for the goal that would see them take the lead.
Bayern continued to create chances with Tolisso again having a chance however his shot was straight at Finn Dahmen in the Mainz goal.
Just past the half-hour mark, the match had its first goal. A long ball was played to Burkardt who shook off Jerome Boateng on the edge of the box and rifled his shot past Neuer to give Mainz a lead that was not unsurprising. Bayern players were up in arms as they felt Boateng was fouled in the lead up however the goal stood.
Bayern continued to play a high line and again they were caught out. It was the eighth consecutive match in which they had gone behind in the Bundesliga, a worrying trend for Hansi Flick’s side.
Bayern continued on the front foot as they looked for an equalizer however just before halftime Mainz shocked the champions again and doubled their lead.
A free-kick from Daniel Brosinski found the head of Alexander hack and the defender powered his header past Neuer as Mainz went into the break with an incredible 2-0 lead.
Hansi Flick made two changes at halftime, bringing on Niklas Sule and Leon Goretzka for Jerome Boateng and Benjamin Pavard as he looked for a spark to get his side into the game.
Bayern looked menacing from the outset at the start of the second half and it took them just four minutes to get a goal back. A move that started with Kimmich ended with Lewandowski finding him to head home Bayern’s first goal of the game.
Just five minutes later Bayern was level. Leroy Sane picked up the ball, cut inside, and curled home his shot as he welcomed his return to the starting side with a goal.
Bayern was fully on top however Mainz was still a threat on the counter but just nine minutes later the champions thought they were ahead after a Barreiro own goal, but Alphonso Davies was deemed offside in the build-up.
Six minutes later however, Bayern did have their lead. From a corner, Thomas Muller headed down for Niklas Sule who lashed home his shot via a deflection as they finally took the lead.
With Bayern fully in control, they added another just four minutes later thanks to a Serge Gnabry driving run and he was brought down by Barreiro in the box. Robert Lewandowski stepped up and duly converted for his 18th goal of the season to make it 4-2.
With eight minutes remaining Bayern had their fifth. After a great Jamal Musiala ball found Muller out wide, he clipped in an inviting ball which found Lewandowski who slotted home his second of the game to cap off a truly dominating second-half performance for the hosts as they surged back to the top of the Bundesliga.
There will be serious questions over Bayern’s defending but there can be no doubt over their attacking power as they overwhelmed Mainz with five second-half goals.
Up next for Hansi Flick’s side is a trip to Monchengladbach on Saturday.
