The Spain international has struggled to find consistent form since he moved to Chelsea FC from Real Madrid in a £60m deal under Sarri’s predecessor Antonio Conte in 2017.
Morata netted seven times in his opening seven games in the Premier League last term but the 26-year-old finished with 11 goals in 31 appearances in his debut campaign in the English top flight.
The former Juventus striker fell out of favour in the second half of the 2017-18 season to raise questions about his long-term future at the west London side.
Morata has started seven times in the Premier League since Sarri took over the reins from his compatriot in the summer, while he has made a further three appearances from the bench.
The Chelsea FC forward has scored five goals in the English top flight despite concerns about his confidence and form, including a brace in a 3-1 victory over Crystal Palace at Stamford Bridge on Sunday afternoon.
Asked if there are similarities between Morata and Drogba during his post-match media conference at Stamford Bridge, Sarri replied: “Physically not perhaps.
“Drogba was one of the best in the world for 15 years but Alvaro is very fast, not in the first two or three steps, but if he has to run for 40 metres. He’s strong but not like Drogba, Drogba was too much.
“For Alvaro, goals have to be a consequence, he has to play for the team and his team-mates without thinking about goals.
“That is a consequence of the team and the individual performance. He’s a little bit fragile from the mental point of view but he’s very young and he can improve very fast.”
Morata has netted three times in his last four games in all competitions, prompting hopes from Chelsea FC fans that the Spanish forward may have turned a corner at the west London side.
And Sarri admitted that Morata has benefitted from a surge in confidence over the past month or so to help the Madrid-born striker find his form in front of goal.
“Alvaro has improved in the last month in confidence and personality,” Sarri added.
“He has also improved from the technical point of view, now he’s able to play more with the team. He has great physical and technical potential and I think he can improve more.”
Chelsea FC finished in fifth spot in the Premier League table last term to miss out on a place in the Champions League for the second time in three seasons.
Sarri’s side will welcome Everton to Stamford Bridge in the Premier League next weekend as the Blues look to maintain their unbeaten start to the season.
