Chelsea hero Jimmy Floyd Hasselbaink insists Pierre-Emerick Aubameyang can prove a successful signing.
Aubameyang is waiting for his first goal after arriving last month from Barcelona.
Hasselbaink, 50, who racked up 70 Premier League goals in 136 games for Chelsea, said: “Aubameyang did really well at Barcelona. He was scoring goals. It's a good signing for the next two years.
“I don't think that it is a four or five-year signing. It's a two-year signing. I think he will score goals; he knows where the back of the net is.
“He did sign for Chelsea because Tuchel was there but as a footballer it happens that managers come and go. His career will keep on going and he needs to produce like any other player.. and I don't think that is a problem.
“Aubameyang can score 20 plus goals. Have they got a squad to go and become champions? Not yet.
"Have they got a squad to get in the top four and compete for an FA Cup, or get far in the Champions League? Yes.
"Are they going to win the Champions League? They're not favourites, I don't think that they are. But a successful season would be finishing in the top four and winning a cup this year."
