It cannot have been easy for Shinji Kagawa to leave Manchester United, but if his performance in his first game since returning to Borussia Dortmund is anything to go by, the move is definitely in his best interests.

Kagawa scored a goal and set up another in Dortmund's 3-1 win over Freiburg on Saturday, marking an impressive second debut for the club that he left to join United in June 2012 only to return at the end of last month when things went sour at Old Trafford.

"Kagawa moved like a fish caught in a net," ran a match report in Sunday's Nikkan Sports. "His presence in front of goal was unlike anything you could have imagined during his Manchester United days. His goal came from the kind of perfect combination he used to be involved in in his first spell at the club."
