Mitos execution pinalty CR7

Real Madrid duel cons Paris Saint-Germain (PSG) leaves a lot of stories. Not only the impressive comeback of Real Madrid, but also one of goals scored by Cristiano Ronaldo through a penalty. CR7 execution from the white dot looks weird and seizes the public's attention.
Real Madrid won 3-1 in the first leg of the last 16 of the Champions League on Thursday (15/2/2018) early morning hrs. PSG actually winning first via Adrien Rabiot but Ronaldo's penalty at the end of the first half made the score just as strong. Additional goals from Ronaldo and Marcelo in late second half made the final score 3-1 to Real Madrid win.
Ronaldo's own penalty looks mysterious. In reruns on television cameras, the ball spotted just before Ronaldo kicked. Yes, kick the megabintang at a glance looks like a volley.
I do not know what happened, the article in reruns seen if Ronaldo did not do two touch when executing the ball. Is this just a camera effect, or is Ronaldo cheating?
