Juventus coach Antonio Conte was upset with their performance in victory over Lazio.
Conte felt "regret and even anger" at having to scrape a victory over Lazio when Juventus had dominated the game.
"There is certainly some regret and even anger, as we dominate games and don't close them off, which often ended up in draws. This was heading in a similar direction, as we were in control and not determined enough to get the final blow," he said of the 2-1 win.
"Unfortunately it was happening again today after an excellent first half and we allowed Lazio so little. We have to improve and grow, but the lads are achieving something extraordinary.
"It's inevitable that if we converted all our scoring opportunities, we'd all be calmer and our coronary arteries under less stress! It'd also be fair, as Juventus dominated so much and had to suffer until the final whistle tonight.
"It's ok, as we go back on top of the table and always have Milan's pressure behind us, but it is a good step forward."
