Wolfsburg climbed out of the bottom three of the Bundesliga with a 3-1 victory at Hoffenheim as new management duo Lorenz-Gunther Kostner and Klaus Allofs enjoyed a winning start to life together on the Wolves bench.
Makoto Hasebe, Bas Dost and Naldo each found the back of the net to put the 2009 German champions comfortably clear before Eren Derdiyok netted a late consolation for hosts Hoffenheim.
New director of sport Allofs was taking his place next to caretaker-coach Kostner for the first time since arriving from Werder Bremen during the week.
Allofs' former club Bremen were also victorious on Sunday as they battled back from a goal down to beat Fortuna Dusseldorf 2-1.
Jens Langeneke put Fortuna ahead from the penalty spot in the 11th minute, but goals from Nils Petersen and Kevin de Bruyne earned Bremen all three points at the Weser Stadion to take them up to seventh.
Schaaf was alone on the Bremen bench for the first time in 13 years after the departure of his right-hand man Allofs.
