Even if we do sign Piatek don't expect him to fill Kane's shoes, this will be a signing for the future who 'might' play a role this season, to put that level of expectation on a 24 year old is plain crazy.
24 isn't that young and he's been leading the line for Milan.
Agree that he will need time, but surely we can't be buying him as a 'development player'. We must see him as close to ready.
