Juventus boss Antonio Conte was satisfied with their 1-0 win over Bologna.
Juve won courtesy of a Paul Pogba goal.
"The only thing that counts is to win and that wasn't simple today," Conte told Sky Sport Italia.
"All teams come to the Juventus Stadium in order to defend and create a packed midfield. It's down to us to score early and break that deadlock. We were too slow in the first half, then raised the tempo.
"It's tough against these sides who defend with 10 men. We did well not to lose our heads and prevented counter-attacks. Gigi Buffon was never called into action.
"This side is mature, has grown a great deal and I am happy. All of this explains the extraordinary campaign we're having."
