Former England striker Peter Crouch says Nicolas Jackson is no natural goalscorer.
Crouch insists the Chelsea striker isn't the answer long-term for the Blues in manager Mauricio Pochettino's attack.
Jackson drew another blank as Chelsea were beaten by Brentford on Saturday.
And Crouch insists the summer arrival from Villarreal isn't the answer, telling TNT Sports: "Nicolas Jackson, let's be honest, is not going to be the answer long-term.
"He does a lot of great work outside the box, but is he going to get you 15-20 goals? I don't think so."
