Kevin-Prince Boateng admits he is happy to be back in the Bundesliga after joining Borussia Dortmund on loan from Tottenham Hotspur.
The midfielder has linked up with Dortmund for the rest of the season, with the option of a permanent move in the summer.
He had endured a difficult 18 months at Spurs after joining from Hertha Berlin and is relieved to have secured a return to Germany.
Boateng accepts he has made mistakes during his career and is now aiming to help Dortmund push for a place in Europe.
"I am very happy to be at Dortmund and glad that I have left Spurs," Boateng told Bild. "I definitely wanted to go back to the Bundesliga.
"Three days ago my agent phoned me to prepare myself for a transfer, but a few hours later the deal seemed off.
"But then I got in touch with (chairman) Daniel Levy and requested a transfer. He agreed!
"I have made a lot of mistakes in my career, but I feel I have acquired maturity during my difficult spell at Spurs. I had more than enough time to think about doing better.
"Borussia is lying in sixth actually and still has every chance to go to Europe next season. I want to help them to reach that."
