He'd be fine if we already had a target man striker.
He's hardly ever been a regular starter anywhere as he can't play the lone front man role.
Chatting to seasoned Chelsea fans he's not worked for them as he's not really a target man.
He makes good runs and shows for the ball etc but he's not what they need as back up.
The one caveat is that they said the same about Lukaku and his game developed with time.
