Jurgen Klopp claims that Shinji Kagawa was acquired at the right time and that he will be needed by Borussia Dortmund now.
As the summer transfer window comes to a close, the "yellow-blacks" have reacquired the 25-year-old Japanese player, who spent two unsuccessful seasons at Manchester United.
Within the ranks of the German vice-champions, Marco Reus is currently recovering from injury, so S. Kagawa is likely to step onto the field in the Bundesliga matches happening this weekend.
"We cannot give Kagawa a few more weeks because we need him now," Klopp said. "In the past few days in training, he has made a good impression and shows that he can still offer a lot to our club."
The coach also added: "Of course, we cannot expect Shinji to perform well right from the start and be the same as two years ago."
In the Dortmund team, the Japanese player has already played 71 matches and scored 29 goals.
