The 2014/15 campaign may still be in its infancy, but Mönchengladbach and Mainz 05 are jostling for the leading positions in the Bundesliga after six matchdays. Both have displayed an attractive brand of football which has led to plenty of goals and entertainment, but one of these teams could be nursing their first league defeat during the upcoming international break.

Tiredness and niggles after a UEFA Europa League clash on Thursday night are the main concerns for Gladbach coach Lucien Favre. (pictured) was unable to train on Friday due to a dead leg, while World Cup winner is also rated doubtful. Rotation is almost guaranteed.

(pictured) is set to return for Mainz after missing their 0-0 draw with Hoffenheim, but is still in South Korea having won the Asian Games with his country this week. is back in training, giving Kasper Hjulmand another option at the back.

Master of magnificent goals, added another to his collection against SC Paderborn last time out and the confidence garnered from that game will make him a tricky proposition for the Mainz defence. The Brazilian also has one assist to his name this season.

No Okazaki, no party: Mainz played out a goalless draw against Hoffenheim last weekend with the injured Okazaki forced to watch on from the stands due to injury. He has scored five goals in five Bundesliga games this season to become the most prolific Japanese player in the Bundesliga of all time.

Lucien Favre (Gladbach coach): It's going to be a complicated game because Mainz are hot to handle. It's no coincidence they are so high up the table.

Kasper Hjulmand (Mainz coach): Gladbach are a very, very good team. They're an exciting team with young players who follow an interesting philosophy.

Both are unbeaten in the Bundesliga, but there are still some blots on Mainz's season in the shape of DFB Cup and UEFA Europa League elimination. Gladbach are still in the Europa League, on the other hand, and picked up a 1-1 draw at FC Zürich on Thursday evening.

Gladbach have recently found the key to unlocking Mainz with five wins and a draw in the last six meetings, but they did not always have it their own way against the Rhineland-Palatinate club. In fact, prior to that hot streak, Mainz had won five and drawn three of the previous 10 encounters.

Possible line-ups:

Mönchengladbach: Sommer - Korb, Jantschke, Stranzl, Alvaro Dominguez - Kramer, Xhaka - Hahn, Traore - Kruse, Raffael

Mainz: Karius - Brosinski, Bungert, Bell, Junior Diaz - Moritz, Geis, Baumgartlinger - Djuricic, Hofmann - Okazaki
