The Nerazzurri won 4-0, with Mauro Icardi back on the scoresheet.
Inter are now two points clear at the top of the table and Mancini said: “We had to improve in terms of converting the chances we created and today more than two goals arrived. We deserved the victory and are happy.
“We ran few risks, but in the first half I had hoped to score more and be a bit more relaxed.
“The quality of Jovetic and Adem Ljajic is good for Icardi and will provide him with more service. It'll just take a bit of time."
