Borussia Dortmund secured a last-gasp draw with Bayern Munich on Matchday 9 — and things do not get any easier this weekend with a trip to leaders Union Berlin.

Bayern, meanwhile, face a tricky test of their own as they host second-placed Freiburg.

Eintracht Frankfurt face struggling Bayer Leverkusen, while the Bundesliga's bottom two sides meet when winless Stuttgart play Bochum.

Elsewhere, RB Leipzig will be looking to maintain their recent upturn in form when they take on Hertha Berlin.

Game of the week: Union Berlin vs Borussia Dortmund (Sunday, 4.30pm)

Table-toppers Union are enjoying their best-ever start to a Bundesliga campaign with 20 points from nine games — but they will have to defy more of their own history to get the better of Dortmund.

The Berlin outfit have a worse top-flight loss percentage against the visitors than any other opponent (67%) and have suffered defeat in each of their last three meetings with them.

Additionally, they have not kept a clean sheet in any of their last eight competitive clashes with BVB and have conceded more Bundesliga goals against them (16) than any other side except Bayern (also 16).

However, the league leaders have the best defence in Germany’s top flight this year, conceding just six times and boasting a division-low expected goals against tally of 8.1.

Union are unbeaten in their last 10 Bundesliga home games (seven wins, three draws) and will hope to continue that run against Edin Terzic's men.

Bayern Munich vs Freiburg (Sunday, 6.30pm)

Bayern go into this fixture below Freiburg for just the third time in their history — but they have the chance to leapfrog their opponents with a win.

Julian Nagelsmann's men are enduring their worst start to a season in 12 years. But history is on the reigning champions' side in this fixture, with Die Roten never having lost a home Bundesliga match against Freiburg (19 wins, three draws).

However, the Breisgau Brazilians are one of just two teams who are still unbeaten away from home this term, so will hope to maintain that record in Bavaria.

Freiburg have also scored in each of their last eight clashes with Bayern — doing so again will certainly boost their chances of a positive result.

Eintracht Frankfurt vs Bayer Leverkusen (Saturday, 2.30pm)

Leverkusen's 4-0 win over Schalke last Saturday saw them climb into 15th place and out of the drop zone.

But Eintracht Frankfurt are not the side they would have wished to come against next, as they look to turn that momentum into a positive run.

The hosts have won more Bundesliga home games against Leverkusen than against any other side (21) — and Xabi Alonso's side only have a worse away loss percentage against Bayern (74%) than they do versus this weekend's opponents (57%). 

In fact, Leverkusen have lost their last four trips to Deutsche Bank Park.

However, Die Adler have conceded three goals in defeats to both Bochum and Tottenham in the past week and will be hoping for a positive response.

Stuttgart vs Bochum (Saturday, 2.30pm)

The league's bottom two clubs — Stuttgart and Bochum — face off in a critical encounter.

The hosts sit one place higher with five points to their rivals'  four — but are the only team in the league yet to taste victory.

Bochum have the worst away record in the division (zero points) but come up against the league's worst home side in Stuttgart (two points).

Die Schwaben are unbeaten in their last 23 home games against Bochum in all competitions (16 wins, seven draws). However, they have also failed to keep a clean sheet in any of their last 26 Bundesliga matches at home — a club record.

RB Leipzig vs Hertha Berlin (Saturday, 5.30pm)

RB Leipzig have started tentatively picking up form after a poor start to the season, earning four points from their last two league outings.

And this clash with Hertha Berlin represents a good chance to build some momentum, with Leipzig winning 10 of their 12 Bundesliga matches against the club from the capital (one draw, one defeat) — scoring 45 goals in the process. Both those tallies are higher than against any other side.

Hertha are unbeaten in their last five games but have only won once in 2022-23, drawing their last four in a row.

Leipzig will look to Timo Werner to break that streak, with the striker having been involved in 12 Bundesliga goals against Hertha in his career (eight goals, four assists) — only managing more against Mainz.
