The win puts Al Hilal top of Group D with four points
AS Roma striker Tammy Abraham scored late in the second half to secure a 1-1 draw at Juventus on Saturday, cancelling out an early opener by Dusan Vlahovic as Jose Mourinho's side remained unbeaten after three games in Serie A this season.
With two wins and a draw, Roma remain third in the standings on seven points while Juventus are sixth with five points.
Juve kept Roma's dangerous frontline at a safe distance for the majority of the game as more than 2,000 visiting fans watched their side being outclassed at the Allianz Stadium in Italy's most anticipated clash of the weekend.
"At the end of the first half I told the team that I was ashamed to be their coach," Roma coach Jose Mourinho told DAZN.
"I was praying to get to halftime on 1-0, because after what we had done it was a fantastic result for us.
"In the second half we deserved to win 1-0, but I don't want to say that the draw is fair because that would be giving my team a credit that we didn't get."
The Portuguese tried to inject more energy into his side by bringing on striker Stephan El Shaarawy and youngster Nicola Zalewski after the break but Juve kept pressing and Cuadrado fired just wide.
Roma then equalised against the run of play in the 69th minute following a free kick as Abraham nodded home Paulo Dybala's cross from the right.
Juventus then came close to losing the match when Lorenzo Pellegrini's corner almost went over the line for Roma before being cleared by substitute Arkadiusz Milik on his debut.
"Mourinho told me that they were very lucky in the first half? Yes, they were lucky there," Allegri said.
"When you play a first half like (ours) and you don't close the game, then you can capitulate."
Roma next host newly-promoted Monza on Tuesday while Juve host Spezia on Wednesday.
