Yes that what worry me with Andre Silva he looked really out of his depth Milan and they sold him quicklyDon't buy Frankfurt strikers.
Rebic - nothing special, solid performances at Milan.
Jovic - flopped at Real
Haller - flopped at West Ham
Their system under Kovac and Hütter was very justified for the strikers, don't think he will have similiar numbers in a different club.
Silva wasn't good at Sevilla, wasn't good at Milan.
To risky, despite his very good season.
