Borussia Dortmund coach Jurgen Klopp is expecting a difficult encounter when his side meet Wolfsburg on Saturday in the Bundesliga.
The reigning league champions held Bayern Munich to a draw last weekend and will be hoping to go one better against a Wolfsburg side languishing near the foot of the table.
Despite their struggles however, Klopp believes Lorenz-Günther Köstner's side will pose a problem for his men, who on Tuesday night, defeated Manchester City in the Champions League.
"We have to expect a team that has fun when they play football. Regardless of their situation I believe their team is still behind their coach. For them, some good results are due and they will certainly fight for it," Klopp said in a press conference.
"Wolfsburg have rediscovered the joy of playing football again. This is not good for their opponents. They have always had great quality in their side, but, now everything is easier."
Although asked, Klopp gave little away as to what players he is planning on calling up, though, he did reveal that there may be a change in his side's tactical approach.
"I cannot say definitively who will play. I have the option of playing a 4-3-3. We still have to think about it though as I have not yet decided," he added.
"I will decide closer to the game. Some of my players have a good understanding of this system. I have a team able to change their game with little extra training."
Dortmund are currently third in the Bundesliga and have lost just once at home this season. But Wolfsburg will be buoyed by the fact that 10 of the 16 points they have accumulated so far, have come on their travels.
