The images have been beamed around the world and back again over the past few days. In Saturday's 1-1 draw with Gladbach, Zentner picked up a pass in his penalty area but failed to notice when the ball span behind him. The 23-year-old got a very nasty surprise when the white thing at his feet turned out to be the penalty spot, but he recovered in time to prevent Foals captain Lars Stindl scoring a simple goal.
Watch: Zentner's incredible near miss against Gladbach
Luckily the story has a happy ending. This Wednesday, the 05ers extended Zentner's contract through to 2021, with the club expressing their satisfaction at how well he has performed in the absence of number one keeper Rene Adler. Born in nearby Rüdesheim, Zentner came through the Mainz youth system and returned to the club this summer after a two-year loan spell with Holstein Kiel.
"Robin has made a huge leap forward since returning from Kiel," enthused sporting director Rouven Schröder. "His performances in training this summer were outstanding, and he has really delivered on his potential since coming in for the injured Rene Adler. He has the necessary talent and charisma to succeed at the highest level, which is why we are delighted to retain him on a long-term basis with this new contract."
Zentner has made three appearances for Mainz in all competitions this season, also featuring in the 1-1 draw with Eintracht Frankfurt on Matchday 10 and the DFB Cup victory over his former side Kiel last month.
"Everyone knows things can go very quickly in football," Zentner said. "I've had a chance to showcase my abilities and I think I've done a good job - but I won't rest on my laurels. I see this as an opportunity to progress, and it's really special to be able to it here at my hometown club."
All's well that ends well for Zentner then - now he just has to keep his eye on the ball.
