Giorgio Chiellini is bitter after Juventus failed to beat Brescia last night and subsequently lost ground in the title race.
The Bianconeri did manage to take the lead through Fabio Quagliarella, but a beautiful outside of the foot strike from Alessandro Diamanti allowed Brescia to equalise and draw 1-1 at the Rigamonti.
"If we want to dispute a season in and around the top of the table these [games] are fundamental," Chiellini said.
"We are having a good season, but if we are thinking about making a jump in quality then we cannot afford to waste these chances.
"In one way or the other we should have won in Brescia just like Napoli who have found two wins in their last two away matches despite not shining while we have not gone beyond two draws.
"You can make a mistake once, but it already happened to us in Bologna.
"We shouldn't have repeated this mistake in Brescia. Instead there were too many distractions.
"We must concentrate in the same way as we did against Milan and Inter against Cesena and Brescia."
When asked if Juventus' injury crisis played a part in their draw, Chiellini said: "The emergency has nothing to do with it.
"We are fine and have sufficient quality to win on these pitches. I think that the errors committed here will not be repeated against Roma, but a great team knows how to suffer and win even in the most difficult situations."
