Borussia Dortmund coach Jurgen Klopp believes his side can learn a lot from their rare defeat last weekend.

The Westphalians' charge towards the title was stalled a little by Hoffenheim and their lead at the top of the Bundesliga was cut to nine points, but Klopp actually welcomed the defeat as a wake-up call to his side.

And he expects to see improvements at the Westfalen Stadion tomorrow against Mainz. "For analysis purposes, the game in Hoffenheim gave us a great deal to discuss," he said. "We have discussed the reasons why the game went like it did extensively. We now have to bring back those percentage points that were lacking against Hoffenheim and made us deserved losers there."

Klopp on last weekend's loss

Mainz coach Thomas Tuchel would have preferred to see Dortmund win that game last weekend as he feels only their third defeat of the season will make them even harder to beat tomorrow. "It is certainly not an advantage for us that they lost that game," he said. "And it would be a huge mistake for us to treat that game as the norm."

Similarly, he does not believe his side's 1-0 defeat to Bayer Leverkusen last weekend was out of the ordinary. "We just made an error and we lost because of it," he said. "Unfortunately, errors are part of professional sport and so we just have to move on. I am glad that we have a big challenge ahead because we are travelling to the league leaders and that makes the game particularly special."

Neither side should be changed from last weekend, although Shinji Kagawa is on the way back from a broken foot and he could soon return to the Dortmund team.
