Ronaldo appeared to have sealed the game for his team, only for Juan Mata’s free-kick and an Alex Sandro own goal to gift United all three points late on.
Speaking after the match, Ronaldo stated that Juventus gifted three points to the Red Devils.
“The Champions League is a special competition, where you could be winning, but can’t relax, as anything can happen,” Ronaldo told Sky Sport Italia.
“We dominated the game for 90 minutes, had so many chances, could’ve killed it off three or four times, but we relaxed and were punished.
“Manchester United did nothing to win the game. You can’t even talk about luck, because you have to find your own luck and in this case we just gifted it to them.
“Now we’ve got to lift our heads, as we played really well and are still top of the group.”
