Munich's "Bayern" coach Josep Guardiola warned his players not to relax during the crucial season battles in the Bundesliga.
According to the football specialist, in this case they could face the fate of "Borussia" playing poorly.
"I like Dortmund's club and their strategist J. Klopp. They have excellent players representing the team, but they are currently at the bottom of the tournament table.
We also need to be careful not to suffer the same fate," Guardiola said.
"If we understand before the match against Gelzenkirchen's "Schalke" that we can experience failure, then we will be on the right track.
This team is one of the strongest in Germany, and in attack we will have to be very patient".
