Thomas Tuchel is confident in Mario Gotze getting back to his best form and becoming a key part of Dortmund.
The Germany international was at Bayern Munich for three seasons but returned to the Signal Iduna Park for the 2016-17 season but has not hit the expectations expected of him.
The 24-year-old has only one goal in 11 appearances and has been relegated to the bench since the mid season break.
Nevertheless, Tuchel has stressed the attacking midfielder should not be written off and needs time to get back to his best after a difficult period.
“I am convinced that we will need Mario at some stage,” Tuchel stated at a news conference ahead of the DFB-Pokal game against Hertha Berlin.
“There are no problems between us. It is just a decision I have made. Others have a bit more confidence right now. Mario is lacking confidence a bit. But he will get his chance and prove his worth.
“There is a lot of attention for what he does, but I do not think this helps him.
“What we need now is patience, diligence and hard work.”
Gotze is being plagued by minor injury problems ahead of Wednesday’s clash at Signal Iduna Park and could miss the round of 16 clash.
“He has some muscular problems and missed Tuesday’s training,” Tuchel added.
“It will be tight if he can play against Hertha.”
