Borussia Dortmund management bear Shinji Kagawa no grudge over his move to Manchester United.
United announced Kagawa's capture this morning.
Borussia sports director Michael Zorc was responsible for bringing the player to Dortmund in 2010.
And he said: "We would like to thank Shinji for his effort and his large contribution in two extraordinarily successful years."
Kagawa was named in the Bundesliga's team of the season for 2010-11 despite being absent through injury for half the campaign.
He then went on to score 16 goals last term, when Dortmund completed the domestic league and cup double.
