Morata made an explosive start to his Stamford Bridge career, scoring six goals in six league appearances at the start of 2017-18, but things quickly soured for the Spain international.
A mysterious back problem blighted much of the campaign and he only scored a further five goals in the top flight and four in cup competitions.
Morata has shown encouraging signs of a return to form since Maurizio Sarri replaced Conte as head coach, however, scoring his first goal of the season in last month's 3-2 win over Arsenal, and he thinks he is better suited to the new system.
When asked if he feels more comfortable with Sarri in charge, he told Cadena SER: "Yes, yes, yes. For me, yes. It's not for nothing, but for the style of play. It wasn't my style of play and I suffered a little because of that."
Morata has previously described how he played part of last season while taking painkilling injections he received from a doctor in Germany, with his form suffering as a result.
The forward, a reported £60 million (€77m) signing from Real Madrid last year, admits he would do things differently if the problem reared its head again.
"In today's world, it's normal that these [critical] things are said," he added. "Chelsea made a huge effort for me and it wasn't returned. I should have repaid them double. A player they pay for can't finish the season with 15 goals.
"People think we're machines. If I had stopped for three months, I would have come back with a clear head, but I was professional and I wanted to give everything.
"If I could go back, I would stop for two months. I was in pain, I went to Germany to see the doctor, paying for private planes. People believe the false life of Instagram, what it shows you; they thought I was at home with my wife. Someday, I'll write a book about what I've been through."
