Shinji Kagawa has already impressed Sir Alex Ferguson during his short time at Manchester United.
The Japan international made a brief appearance as a substitute against AmaZulu but is set to start Saturday's next DHL tour game with Ajax Cape Town.
"There are similarities to Ji-sung Park. They're both disciplined, they work hard," said the boss at a press conference. "He's been outstanding. His training performances have been very good. He was three or four days behind, but he'll play tomorrow.
"We're very pleased. Those qualities that you can compare him with Ji, they're very much the same. They're good professionals, excellent to work with. There will be no problems with him settling into the club.
"What we identified about Kagawa is exactly what I'm seeing now. The difference now is that our players are realising his qualities. He's got quick feet, both footed and had a good goal ratio with Dortmund. He's doing very well and I'm very happy."
The boss will start with his strongest line-up against Ajax Cape Town before giving some of the fringe performers another run-out.
"We'll play our strongest side to begin with tomorrow and introduce some young players later on," he added. "We've brought more than 20 players with us. We want to get them all game-time. We always hope we can finish the tour without any injuries, otherwise it's an issue."
