LAST MEETING
October 31, 2010: Mainz 0-2 Borussia Dortmund
Mario Goetze and Lucas Barrios were on target as Borussia Dortmund leapfrogged high-flying Mainz to claim first spot, which they have not surrendered so far. Roman Weidenfeller was one of the heroes for Der BVB as he denied Eugen Polanski from the spot in the first half, preserving Juergen Klopp's men advantage before the restart.
PROBABLE LINE-UPS
Borussia Dortmund: Weidenfeller; Piszczek, Subotic, Hummels, Schmelzer; Bender, Sahin; Goetze, Lewandowski Grosskreutz; Barrios.
Mainz: Wetklo; Bungert, Svensson, Noveski, Fuchs; Polanski, Fathi, Soto; Ivanschitz; Risse, Schuerrle.
Prediction
Juergen Klopp's men will be looking to bounce back from their loss against Hoffenheim last week and so will Mainz. Thomas Tuchel's men rise to the occasion on their travels and will put up one hell of a fight, but Der BVB are likely to edge this one.
Borussia 2-1 Mainz
