The Italian coach concedes his side’s victory was down to individuals and not the team as a whole
Stunning goals from Ronaldo, Dybala and Costa ensured titleholders Juve stayed four points clear of scudetto challengers Lazio thanks to Tuesday’s 3-1 victory at struggling Genoa.
Dybala broke the deadlock with a fine individual effort in the 50th minute before Ronaldo made it 2-0 six minutes later via a thunderous long-range strike.
Juve substitute Costa then put the visitors out of sight with an equally impressive effort, while Andrea Pinamonti drilled in a 76th-minute consolation for Genoa.
“In the second half we lead thanks to our single players because we scored on three excellent plays by three single men,” Juve head coach Sarri said.
“Paulo’s [Dybala] great slalom, the outstanding Ronaldo’s shoot, incredible for its precision and strength and the sensible touch from [Douglas Costa].
“This is how we solved the match, thanks to our individualities and phenomenal skills. We created the team’s assumptions.”
Ronaldo was also scrutinised but Juve have now won three consecutive matches to be top of the table with nine fixtures remaining.
The five-time Ballon d’Or winner equalled his tally from last season across all competitions with his 28th goal in 2019-20, while he has scored 14 goals in 2020 – more than any other Serie A player this year.
Sarri added: “After the lockdown I made an assessment: I said that something changed. Then everybody almost made fun of me because we lost the Coppa Italia on penalties.
“The truth is that once we improved our condition we started paying better this kind of football. This due to our condition that’s getting better after the lockdown.”
