Borussia Dortmund coach Jurgen Klopp admits he keeps in regular touch with Manchester United midfielder Shinji Kagawa. Klopp has admitted trying to tempt Kagawa back to BVB this summer.

"We still keep in touch," he told "It's a bit difficult to speak to him directly, largely because his German hasn't dramatically improved while he's been in England.

"Talking to him on the phone isn't what you'd call a piece of cake. I often have a few words with Shinji's agent, Thomas Kroth, as well. Believe me, I'm always right in the picture about what the lad's up to."
