  • The record between these clubs in competitive fixtures is even at six wins a piece (D3). In the Bundesliga, Mainz have six wins to Leverkusen's five with a 21-20 goal difference.
  • Four of Mainz's six wins against Leverkusen have come at home (D1, L2). Both of the last two meetings in Mainz were won by the home side (1-0 in March 2013, 2-0 in August 2011).

  • Only once have Mainz had more points after five games than they do currently (9). In 2010/11, they had 15 points which saw them end up 5th in the table – the club's best finish.
