In only the third minute of the match, the Portuguese talisman's free-kick was spilt by Lokomotiv goalkeeper Guilherme Marinato.
During the confusion over the celebrations, Ronaldo raised a smile but wouldn't have been happy at seeing a goal "taken" away from him.
Ronaldo - who was denied breaking the record for scoring against the most clubs in the Champions League by Ramsey's final touch in the first half - improved after the break.
However, replays indicated that the ball was already past the goal line, and even Ramsey pointed towards Ronaldo, signalling that his teammate had scored the goal.
England collapse to give New Zealand T20 series lead
This is also the second-highest total by any team against New Zealand , behind Australia's 245 for 5 in Auckland past year . Chris Jordan got two, Sam Curran one, Tom Curran one and Pat Brown also got one wicket each.
Juve's lead lasted just nine minutes, though, as the host levelled through Miranchuk, who followed up to place home after initially heading Maciej Rybus' cross against a post.
Wojciech Szczesny was required to save from Grzegorz Krychowiak at the other end, with Leonardo Bonucci clearing the follow-up from Joao Mario off the line. First, check out the goal and then we will see what Ramsey has to say about the goal. Douglas Costa snatched the victor deep inside stoppage time, after Aaron Ramsey grabbed the opener in the opening minutes of the first half. Aaron Ramsey and Adrien Rabiot were also handed starts.
The goal still gave Juventus a 1-0 lead, so Ronaldo can't be too upset, right?
Lokomotiv Moscow vs Juventus ended in a narrow 2-1 victory for Maurizio Sari's men in a tough Champions League encounter held on Wednesday night, November 6, 2019.
