This weekend will see the league leaders facing the relegation candidates, but there will be another story line taking place in the background.

On Sunday, two sides with contrasting fortunes will lock horns. On one side will be Bayern Munich, who are on course to win the Bundesliga title for an unprecedented tenth straight time. On the other, struggling Greuther Fürth, who are playing in the Bundesliga only for the second time. 

Greuther Fürth currently find themselves in dire straits, as they are firmly rooted to the bottom of the table. That's despite their losing just one of their last five games as they now mount a desperate bid to turn things around and pull off what would be a huge great escape. Certainly, with Bayern stumbling in a surprise 4-2 loss to Bochum recently, Greuther Fürth will hope to take some hope from that as they aim to stage what would be a very unlikely upset.

The David vs Goliath clash that's in store at the Allianz Arena isn't the only story that fans will be watching on Sunday, however.

In addition, a sibling rivalry will be taking place. The Tillman brothers, who play or have played for Germany's youth teams, could be on opposite sides of the pitch.

Timothy, who's the elder of the two, plays for Greuther Fürth. The 23-year-old did play for Bayern Munich - both as a youth and for the reserve teams, so he'll certainly be hoping to get one over on his former side - as well as his younger brother. Meanwhile, 19-year-old Malik began his youth career with Greuther Fürth and now is on the books for Bayern, where he featured for the reserves before being promoted to the senior squad at the start of this season.

So, it'll be more than three points at stake when Bayern Munich and Greuther Fürth take to the pitch, and a case of divided loyalties in the Tillman household. Will struggling Greuther Fürth pull off what would be an impressive upset to give big brother Timothy bragging rights? Or will Bayern and younger brother Malik rebound after a tough week that has seen them fail to win their last two games across all comps?
