Regarding Clyne, we have a Portuguese international player already at the club. Ok he had a mixed first season and with a year of Prem experience under his belt, he can be as good as Clyne. Hopefully the new manager will help his development too.
Kroos not impressed with JK but Loew credits JK with development of his squad
