Because apparently player power is such that 18 year olds on 4.5 year contracts can force moves.Why would even think of selling him when he has not even played for us yet. What is the policy / project if we do. Whole point is to benefit from these young players for years to come. Why would we sell him a top prospect and keep likes of drag and the other lad.
I think we should only even remotely consider selling him if Bayern put in an absolutely absurd, record breaking bid for him. And I highly doubt that will happen.
