The game also hinged upon Liverpool losing their influential forward Mohamed Salah to a serious shoulder injury after tangling with Madrid's Sergio Ramos, a serial victor who knows exactly what to do in the biggest games.
Supporters have called on UEFA as well as FIFA to take action against the Spaniard, who got tangled with Salah in a challenge during the final, causing a shoulder injury to the Egyptian, morale dip for Jurgen Klopp's side leading to Liverpool losing and threat of Salah missing out on FIFA World Cup 2018 in Russian Federation.
"He has done unbelievable this season and for it to end that way for him was devastating", Robertson added.
"Yes of course I'm proud of what we achieved, of how we came to the final, but if you come to the final you want to win it and the farther you come in the tournament the bigger the disappointment will be - especially in the final, if you lose it the disappointment is really big", the Netherlands global said.
"It was an achievement to get here but second is as good as last, in my book", he said.
When asked about the mood in Liverpool's dressing room, Karius said: "There's not much I had to say".
"I'm delighted that Cristiano has five Champions League wins, just like me". We are all so upset. Bale has his moments of genius like Saturday's goal, but is increasingly a super-sub, a player who falls short of the crushingly consistent brilliance of Ronaldo.
"We win as a team, we lose as a team".
"It's not about him and the mistakes he might have made, it's about the team".
We'll have to keep an eye on it in the coming days, but there's no doubt that the comments were poorly timed. He will hold his hands up.
If he goes back to England this summer, Bale would leave Madrid with a curiously lopsided record of four Champions League titles yet only one in La Liga.
"He is young and he will learn from it".
"With Mo Salah we are a better team", the midfielder told Liverpoolfc.com.
"In addition he kept acting that Liverpool players fouled him falsely, causing the referee to give Manne a yellow card he did not deserve. I judged it wrong and it went in".
