Jurgen Klopp says that he is delighted to have created a reunion with Shinji Kagawa this summer.
Kagawa headed back to Borussia Dortmund, where he made his name in European football, during the summer transfer window, and Klopp is grateful that the deal went through.
"I am really delighted that Shinji is back here," he told the London Evening Standard. "With his quick turn of pace in tight spaces, he’ll really do our game good.
"He can set up and score goals. And unfortunately, we now know that Marco Reus will be out for four weeks after damaging his ankle ligaments, so Shinji’s transfer is all the more timely."
Kagawa has wasted no time settling back into life at Dortmund, as he scored in his first game back at BVB at the weekend.
His transfer back to the Bundesliga brings to an end a what was a disappointing time in England, where he struggled to make the impression desired.
Kagawa was brought to Old Trafford as a player who could add a new attacking dimension to the squad, but he failed to make an impression in English football.
The Japanese international never forged a starting place for himself, and he was not provided with as many first-team opportunities as he would have expected when moving to United back in 2012.
It must be said that his failure in Manchester was not all his fault. Kagawa was regularly deployed out of position on the wing during his time at the Red Devils.
However, his performances when occupying an attacking midfield slot failed to make an impression and, as a result, he was allowed to leave this summer when Louis van Gaal took charge.
The Dutchman brought in a host of attacking talent in his first transfer window in charge, and it led to Kagawa being deemed surplus to requirements.
He has returned to Dortmund with a point to prove, and he can show United exactly what they are missing when Klopp's men take on English opposition tomorrow night.
The Bundesliga runners-up face Arsenal in the Champions League, and Kagawa will be aiming to prove that he can perform against Premier League sides.
