BVB Dortmund coach Thomas Tuchel is hoping that midfielder Marco Reus can rediscover his form against Bayern München on Sunday.
Reus is currently on a four-game scoreless streak as he failed to find the back of the net during his side's 1-1 draw with PAOK in the Europa League on Thursday.
However, Reus has scored seven times against Bayern in his career and Tuchel is confident that the 26-year-old will add to that tally at the Allianz Arena on Sunday.
"I always have the hope that Marco explodes," Tuchel told reporters. "It is true that he is struggling right now.
"We see in his analytic stats that he is working very hard and how he fights and he will come back, hopefully, tomorrow."
Meanwhile, Tuchel also believes that Bayern coach Pep Guardiola is in a league of his own and added that the 44-year-old was at his prime when he was coaching Barcelona.
"He is the best, even if he doesn't want to admit it himself," Tuchel said. "I've always been a fan of Barcelona. Barcelona under Pep was the benchmark for me."
