- Frankfurt four points off relegation play-off place.
- Eagles have lost their last three in the league.
- Mainz's 3-2 defeat to Köln was their first loss in four.
Rhine-Main bragging rights could hold added significance for Eintracht Frankfurt and 1. FSV Mainz 05 on Sunday (kick-off: 17:30CEST/15:30GMT).
Second-bottom Frankfurt were cast six points adrift of outright safety following their 3-0 defeat to Bayer 04 Leverkusen coupled with relegation play-off spot incumbents SV Werder Bremen's rousing 3-2 victory over VfL Wolfsburg last weekend, and can scarcely afford any further slip-ups as they bid to avoid dropping down a tier for the fifth time in their history.
Mainz's prognosis is much more favourable, despite surrendering a two-goal lead in their 3-2 defeat to 1. FC Köln on Matchday 30. The sixth-placed 05ers currently occupy the final UEFA Europa League qualifying berth, but do so as one of three sides locked on 45 points, only four behind fourth-in-the-table Hertha Berlin.
Matchday 14 rewind: Mainz 2-1 Frankfurt
Yoshinori Muto and Yunus Malli scored either side of Alexander Meier's 40th-minute sending off as the ten men of Frankfurt fell to a 2-1 defeat at the Coface Arena - Haris Seferovic reducing the arrears in the second half.
Matchday 31 - match stats
- Eintracht Frankfurt come into Matchday 31 in 17th, six points behind VfB Stuttgart and the safety of 15th place.
- Niko Kovac has lost 80 percent of his games since succeeding Armin Veh as Frankfurt coach in March. This is the poorest record of any Eintracht coach.
- The Eagles' 3-0 loss at Bayer 04 Leverkusen last Saturday was their third consecutive defeat.
- The Hessians have won only one of their previous 12 Bundesliga games - a 1-0 triumph over bottom club Hannover 96 on Matchday 27.
- Mainz have only won one of their last five away games, though that was an impressive 2-1 victory at champions FC Bayern München on Matchday 24.
- Frankfurt have won just one of their last eight games against Mainz - a 2-0 victory in April 2014. However, Mainz have won only one of their last 11 matches at Frankfurt's Commerzbank Arena, prevailing 3-1 in November 2012.
- Frankfurt's Meier is the only player to have played in all 15 Bundesliga encounters between Eintracht and Mainz. He has scored five goals against the 05ers.
- The reverse fixture, which Mainz won 2-1 on Matchday 14, saw Meier sent off in the 40th minute for a second bookable offence. It was the 33-year-old's first and hitherto only red card in the Bundesliga.
- Frankfurt have the worst record in the away table, with only nine points picked up on the road this season.
