Having overturned a 3-0 first-leg deficit at Real's Bernabeu stadium on Wednesday, Juve were cruelly knocked out by a soft penalty converted by Cristiano Ronaldo in stoppage time of the quarter-final second leg.
Oliver pointed to the spot after judging Juve defender Medhi Benatia to have fouled Lucas Vazquez as the half-time substitute attempted to convert Ronaldo's imperious knockdown.
The tongue-in-cheek inference is that Michael Oliver - the English referee who awarded the late penalty and send of Gigi Buffon - was not qualified to officiate the match.
"I don't understand why they protested the penalty", Ronaldo said.
The penalty came as Vazquez was in position to score in front of the goal after Ronaldo headed down a cross into the area.

Real Madrid now joins the likes of AS Roma from Italy, Bayern Munich from Germany, and Liverpool from England to battle for a place in the final which will be played in Kyiv.
Midfielder Luka Modric has also been omitted from Zinedine Zidane's 19-man group for the trip to La Rosaleda.
"He's a magnificent player and this perhaps wasn't his last Champions League appearance". Real Madrid's attack was noticeably more quiet after the first 15 minutes, and he even provided the assist for Mario Mandzukic's second goal. The referee blew the whistle and you can't change that.
"I don't think that he deserves to go out in this way, but there's no going back on it now". Juve beat us and made things very hard for us with their tactics but our willingness to keep trying to get back in the game eventually gave us our goal.
Star forward Cristiano Ronaldo stepped forward and sent the ball into the net to send the Bernabeu faithfuls into a frenzy. We were not good, and we have to admit that. For the penalty, my heart was beating hard, but I tried to stay calm. Despite this, the 33-year-old got his opportunity to make the difference right at the end, after calmly slotting in the match-winning penalty in the 97th minute.
