Munich - With just four points separating 13th-placed Hannover 96 and an Eintracht Braunschweig currently propping up the rest of the league, it is many a year since the Bundesliga has seen such a densely-packed relegation scrap with just a handful of matches to go.

Accordingly, has more on that and other fascinating tidbits from Germany's top flight ahead of the next round of action:

A mere four-point span covers the bottom third of the table going into Matchday 30, with current cellar dwellers Eintracht Braunschweig only two shy of the safety of 15th place. All of which adds up to the most tightly-packed Bundesliga relegation contest at this juncture for 33 years! Last season, by contrast, 15 points separated the teams in 15th and 18th places with five games to go.

FC Schalke 04 open the weekend programme against Eintracht Frankfurt. The last time these two met six goals were scored, but the points were shared in a 3-3 thriller as Benedikt Höwedes scored an 86th-minute equaliser. All-in-all, Schalke have an excellent recent record under Friday night’s floodlights, winning seven and drawing the other three of their last ten fixtures.

Since bowing out of the UEFA Europa League, Eintracht Frankfurt have collected , an average of just under two a game. Extrapolated across the entire season, that would have added up to 63 points for Armin Veh's side – without a doubt enough to earn them another stint on the European stage.

A couple more close encounters with the woodwork in the 2-0 home loss to Mönchengladbach took 1. FC Nürnberg's tally of post- and crossbar strikes up to 23 for the season. That's a division high – as, incidentally is the tally of 18 racked up against them by the combined opposition in those matches. Borussia Dortmund hold the season record for hitting the woodwork since information started to be collated on such matters 20 years ago. In 2011/12, they did it no fewer than 25 times.

For the second time this season, Eintracht Braunschweig have gone three games unbeaten. In fact, the bottom club's return of seven points from a 3-1 win against Mainz, a 1-1 draw at Leverkusen and the most recent 3-0 success against Hannover makes them THE form side of the last three Bundesliga matchdays!

Borussia Mönchengladbach's 2-0 win at Nürnberg was their 49th in 109 games under Lucien Favre. That works out at a 45 percent victory rate for the Swiss tactician, a figure bettered only by legendary Foals coaches Hennes Weisweiler (50 percent) and Udo Lattek (48 percent).

Mirko Slomka will be back on very familiar territory when Hamburger SV step out at Hannover 96 on Saturday. Slomka was head coach of the Lower Saxony club for four years until the parting of ways on 27 December last year, accumulating a club record 135 Bundesliga appearances on the touchline.

Hamburg midfield prospect Hakan Calhanoglu has hit the net nine times already in his debut Bundesliga season and the latest sweet strike, in the 2-1 victory over Leverkusen, was his fifth from outside the box – a division best.

FC Bayern's record unbeaten run may be at an end, but Franck Ribery's individual one continues apace. Having been rested for the 1-0 loss at Augsburg, the French wing wizard will be looking to make it 50 Bundesliga games without defeat should he be fit and selected against Dortmund this weekend.

Heung-Min Son is on the brink of his 100th Bundesliga appearance. In the first 99, Leverkusen's South Korean shooting star has scored 29 goals and laid on five more.

Hajime Hosogai was only involved in 17 of Leverkusen's 34 games last season, eight stints off the bench included. Since moving to Hertha Berlin though, it has been a different story altogether for the Japanese holding midfielder, who has started all but one of the capital club's 29 matches to date. Hosogai's sum total of 306.8 kilometres also makes him Hertha's hardest-running player this season.
