Dortmund - Some of the Bundesliga's most famous Far Eastern stars come face to face in Borussia Dortmund's clash with floundering 1. FSV Mainz on Friday night (kick-off 20:30 CET/ 19:30 GMT). looks ahead to a game with a more than just your average dose of Asian spice...

Momentum is the key for relegation play-off place incumbents Dortmund as they look to record their first set of back-to-back league wins since September. Visitors Mainz have hardly been blessed with good fortune of late and now sit just three points above the drop zone in 13th.

Jürgen Klopp has no reason to make any changes to the starting XI that beat SC Freiburg so convincingly on Matchday 20. Jakub Blaszczykowski was a second-half substitute a week ago, but sits this one out because of sinus problems. Erik Durm, Kevin Großkreutz, Sven Bender and Sebastian Kehl remain sidelined.

Jonas Hofmann is in line to face his parent club after injury, but there'll be no Loris Karius following the 21-year-old custodian's red card against Hertha Berlin. Greek goalkeeper Stefano Kapino will come in between the sticks and could be joined in the starting line-up by South Korean duo Joo-Ho Park and .

scored the opening goal at Freiburg, before disappointing some of his big-name suitors by putting pen to paper on a new contract at his boyhood club. The move could hardly have come at a better time for BVB, a side whose form more often that not mirrors that of their prized No 11.

The same could be said of the 05ers, for whom eight-goal leading marksman hasn't found the net since 7 December. Encouragingly for the visitors, however, the last two occasions in which the Japanese international went five or more league games without scoring, he came out the other side by grabbing a brace.

(BVB midfielder): "The 3-0 win against Freiburg and Marco Reus contract extension will hopefully give us momentum in the relegation battle."

Kasper Hjulmand (Mainz head coach): "We'll be the underdogs in Dortmund, but I have faith in the quality of our team."

Dortmund recorded their first league win of the year and only their fifth of the season at Freiburg last time out. Mainz were beaten 2-0 by Hertha Berlin, with Matchday 18's 5-0 success over SC Paderborn representing their only win in their last 12 competitive outings.

Mainz enjoyed a rare 2-0 success at home to Dortmund on Matchday 4 that brought an end to their long-running hoodoo against BVB. Until September, Borussia had won seven and drawn one of their last eight encounters with the Karnevalsverein.

Possible line-ups:

Dortmund: Weidenfeller - Piszczek, Subotic, Hummels, Schmelzer - Gündogan, Sahin - Kampl, Kagawa, Reus - Aubameyang
