Was Kagawa scared to let go when Klopp hugged him?

And we all thought Jurgen Klopp was such a nice guy. He talked about how him and Shinji Kagawa cried in each other's arms when Kagawa was sold to Manchester United, he likened Bayern Munich to a James Bond villain, and turned down loads of big clubs as he was interested in the 'special project' at Dortmund.

But he's an angry man (although issued a very genuine apology accepting all the fault).

The fourth official did well to not react, although various reports suggest he changed his shorts at half-time.
