Shinji Kagawa insists he wants to stay with Borussia Dortmund.

The former Manchester United midfielder was back in action for BVB last week, scoring twice in victory over Champions League opponents Legia Warsaw.

"I want to show that I can perform here and I will give everything. I needed those goals last week to pick up my self-confidence," said Kagawa.

"It was an important match for me.

"I've had a few chances this season, but have not taken them. It's been tough. I know I have to improve myself."
