They don't want Kagawa.
Hans-Joachim Watzke : We have worked with Marco Reus as a number 10 which…everyone is talking about. And we have Henrikh Mkhitaryan who can also play there. Would then a third number 10 still make sense?”
Hummels could move, there's always a minor chance. But only if he desperately wants to (Klopp is a nice guy and probably won't block the transfer) and for David Luiz type money.
If BVB doesnt want Kagawa I cannot understand how some posters here think we can get him for under £35-40m
Having said that, we have the money and he is worth it.
