Gianfranco Zola knows a thing or two about scoring goals in a Chelsea shirt, that’s for sure.
The Italian spent seven years at Stamford Bridge, finding the net 80 times for the club before departing in 2003.
However, Zola returned to the club to take up an assistant first-team coach role in the summer, 15 years after leaving as a player.
His task now is to help Chelsea’s current stars shine on the big stage.
And one man he is keeping a close eye on is Alvaro Morata.
Since arriving in London in 2017, the Spaniard has found life difficult.
The forward, who only has five league goals to his name this season, returned to the starting line-up after a spell on the side-lines against Southampton on Tuesday.
And Zola still believes Morata is one of the best in his position technically but feels that he needs to improve tactically if he wants to regain his form.
Speaking to Sky Sports, the former Chelsea star said: “Technically Morata – and this is the reason we invested a lot in him this year – we thought he was the perfect number nine for us.
"Maurizio has always said that. Technically without doubt he is one of the best in this position.
"I think he has to improve a little bit tactically because nowadays with the type of football, football is so organised you need to get better tactically, your ability is not enough.
"In my opinion he needs to improve on this. He's been working on that, he has a good attitude. He feels that he doesn't score enough and he feels a lot of responsibilities for that.
"But he has to learn to put everything behind because these are only burdens that you take on the pitch and they don't help you to perform better."
Zola also highlighted his lack of confidence this season but feels he should use the pressure as motivation.
"It should be a motivational thing," he added.
"You are at Chelsea, you are not playing for Southampton or Brighton with all due respect to those clubs.
"People expect a lot from the number nine at Chelsea. They expect a lot of goals and good performances. This is normal, he has to get used to it.
"If he goes to another big club it'll be the same - there is no way you can avoid your responsibilities.
"It's part of your job and if you can handle that then the better you're going to be."
Morata is likely to feature again for the Blues when they welcome Nottingham Forest to Stamford Bridge in the FA Cup this afternoon.
