Borussia Dortmund defender Neven Subotic has said that former teammate Shinji Kagawa will be a "special" player for Manchester United.
Kagawa, 23, joined the Red Devils last month for an undisclosed fee.
He helped Dortmund to their second-straight Bundesliga crown alongside Subotic, who feels that Kagawa's quality will shine through at Old Trafford.
"He can be a really special player for Manchester United," Subotic told ESPN. "He came to our league having mainly played in the second division in Japan, but still had an immediate impact.
"He played such a big role in our success and he's still so young - he can definitely have a similar influence at United if he is given the chance.
"Of course, it will be harder than here. But if he's given time then there's no doubt the team will see the quality he has."
Kagawa will be hoping to impress on the club's pre-season tour.
