Cologne - What has Robert Lewandowski done more than any other player this campaign? How many matches has it been since Hamburger SV scored a goal? And when did FC Schalke 04 last pick up a Bundesliga win?

5 - Hamburger SV have equalled their own club-low of five consecutive games without scoring. That record was set earlier this season, between Matchdays 1 and 5.

17 - HSV also added to their own record after a 17th game this season without scoring. With 16 goals after 28 games, only Tasmania Berlin of 1965/66 have a worse return than the Red Shorts at this stage.

100 - On the occasion of his 100th Bundesliga appearance, 1. FSV Mainz 05’s Ja-Cheol Koo scored his first brace.

2 - For the first time this season, VfB Stuttgart have won back-to-back home games. Huub Stevens’ men have, therefore, picked up as many points (six) from the last two on home turf as in the other 12 games at the Mercedes Benz Arena this season combined.

1 - Pierre-Emile Höjbjerg scored his maiden Bundesliga goal in his 27th game.

4 - For the first time since Roberto Di Matteo took the reins as head coach, FC Schalke 04 have gone four games without a win.

19 - SV Werder Bremen netted their 19th goal this season from a set-piece in the 3-2 defeat at Stuttgart.

6 - In their 11th Rückrunde encounter, TSG 1899 Hoffenheim slumped to a sixth defeat - meaning Markus Gisdol’s side have already lost more in 2015 than they did in the entire Hinrunde (five defeats).

28 - Oscar Wendt scored Borussia Mönchengladbach’s first goal in the first minute of a match for over 11 years, in the process finding the net for the first time in 2015 after only 28 seconds against Borussia Dortmund.

26 - With 26 points already this calendar year, Gladbach are the Rückrunde’s second-best side. The Foals have only ever once picked up more points under Favre in the second half of a season: in 2011/12 (27).

4 - For the fourth time this season, Robert Lewandowski (r.) scored in the opening quarter-hour of a game - a league-high.

7 - Köln are unbeaten in their last seven games at the RheinEnergieStadion (two wins, five draws), and have picked up three points in their last two home games on a Sunday.

42 - Hoffenheim fired in 24 shots to 1. FC Köln’s 18 on Matchday 28 - a new season high.

2 - Bas Dostassisted two goals for the first time in his Bundesliga career.

1 - FC Augsburg have only won one of their last nine games and have only taken one point from their last four.

2 - For the first time ever in a Bundesliga match, Mainz were awarded two penalties.

2 - SC Paderborn 07 scored two headers in one game for the first time in the club’s Bundesliga history.

5 - Paderborn also celebrated their first goals on home turf this year and a first home win in over five months. The last was a 3-1 success over Hertha on Matchday 10 (2 November).
