Balanced record
The Werkself and Mainz 05 have met 22 times in the Bundesliga – and the record could not be more evenly balanced. With four draws both sides have won nine games each to date. And there is no winner when you look at goal scored: Both Bayer 04 and Mainz have found the back of the net 32 times. And it can come as no surprise that the record in the Palatinate is also evenly balanced: There has been one draw and five victories each for the two teams.
Advantage for the Werkself?
In spite of the overall record it is possible to identify an advantage for Bayer 04: There were two away wins in games against FSV last season: Leverkusen came back from 2-0 down in the first match and Mainz took three points from the BayArena with a 2-0 win in the return game. In addition, the Werkself have won three of the last four away games at Mainz with FSV winning the other.
Goals guaranteed
With just one exception (0-0 in Leverkusen) there has always been at least one goal in the 22 Bundesliga meetings and the fans have witnessed 11 goals in the past three encounters. In addition: The Werkself have scored in each of the last seven league matches – the longest run in 2017.
