Cristiano Ronaldo scored a hat-trick to become the first man to reach 100 Champions League goals as Real Madrid overcame 10-man Bayern Munich 4-2 after extra time in Tuesday's quarter-final second leg to advance 6-3 on aggregate.
Among Ronaldo's three goals, the Portuguese's second and third goals were offside, whilst visitors Bayern had Arturo Vidal sent off five minutes from the end of normal time.
"It's very harsh. They are two offside goals, the bad red card, Casemiro should have been sent-off before me and it makes a big difference", Vidal added.
"When he has to be, he is".
"Sometimes when he doesn't score we wonder what's happening to him".
Gerard Pique, who has been a critic of Real in the past, tweeted "when Ronaldo's 76th-minute goal, which was shown to be offside by TV replays, was allowed to stand".
Zidane though played down his side's controversial win saying it was deserved. "The team was good, we played well and obviously I'm happy with the goals".
In the first half we could have scored one or two goals; it was the same in the second half, but we conceded.
And Vidal vented his fury after the match, per Marca: "This robbery can not happen in the Champions League, it was clearly noticeable and it starts to make you doubt [the game] a bit".
Juve are through to the final four of the competition after holding Barcelona to a goalless stalemate at Camp Nou on Wednesday evening, meaning that they progressed with their 3-0 win from the first leg in Italy.
"We had thought of everything going into this game - except the referee", Carlo Ancelotti said in press conference.
"Bayern feel the behaviour of the Spanish police is utterly out of place and excessive, and have lodged a complaint with UEFA about the actions of the Spanish police".
"If you look at the displays turned in by (Jerome) Boateng, (Robert) Lewandowski (both of whom had faced races to be fit for the clash due to thigh and shoulder injuries respectively) or Manuel Neuer I can only take my hat off".
Ancelotti will also reflect that his best eleven is very close to the required standard, even if depth in his squad to cope with two or three important absences is not there. "The goals, the way he finishes them, in such key moments".
