There were suggestions, as the assembled press tapped away at their laptops inside La Ceramica on Tuesday night, that it had all got too much for Liverpool's Luis Diaz at full-time.
Seeing himself officially declared as a Champions League finalist was, according to some inside Villarreal's stadium, a moment that had brought Diaz to tears.
So moved was he at confirmation of Liverpool's place in Paris that the Colombian winger was overcome with emotion while his younger brother and agent, Raul de Pais, watched on inside the ground.

"I'm going to play in a Champions League final, it's like I always dreamt," Diaz told UEFA after the game.
The full-time images were inconclusive, but if Diaz was in fact reduced to tears after helping the Reds to a 3-2 win over Unai Emery's men, then there can be few who will blame him. The 25-year-old has been simply sensational since joining from Porto at the end of the January transfer window.
This showing in Spain was the latest dossier of evidence to support that claim. Without his introduction at half-time, Liverpool's quadruple dream might have ended in the modest setting of that quiet town on the east coast of Spain.
Like the very best January signings, Diaz has given his new team the impetus to finish the season strongly and few have ever finished stronger than this current Liverpool team are right now.
His direct nature and his fearless, tenacious mentality underpin the flair, the imagination and the eye for goal. It's quite the potent combination when it all comes together, just like it did at El Madrigal in the second period.
“I get it from La Guajira," he says. "It comes from my roots. I always played football in my town, in my homeland. They are my characteristics, they have instilled in me several things that I have today and now I have grown much more. That's my game."
“He has been special," Andy Robertson said in the post-match press conference. "We've tried to help him as much as we can, all the players. We know how difficult it is coming in January. The coaches and everyone else have got him up to speed but he is a special, special player."
Klopp has actively made a point of not burdening Diaz with a list of tactical instructions for when Liverpool are out of possession. Instead, the South American has simply been encouraged to play his natural game. One that, quite handily, matches up almost perfectly with how the Reds press from the front and hunt tirelessly in packs.
That is something Robertson certainly agrees with as a player who is feeling the benefit of the left-sided Diaz more than most in this Liverpool team just now.
"The talent he has and the will to win - he just fits us perfectly," he says. "He played on the left, started pushing them back, dribbling the ball and everything. A really good half from him. He's been special since he came in and it's been a pleasure to play with him."
Klopp has taken the decision to hold off until pre-season to burden Diaz with more information of what he wants from his No.23 and the decision to allow the former Porto man that kind of almost unique freedom within this Liverpool set-up has been inspired.
His header past Geronimo Rulli to make it 2-2 on the night will rightly draw the attention but it was his all-round game that enabled Liverpool to wrestle back the initiative after an error-strewn first half that must rank as the worst of the campaign given the magnitude of the fixture.
Diaz tormented Juan Foyth down Villarreal's right, going through his vast array of movements to push Emery's men into retreat and help Klopp's men get a foothold in the tie; one that was enough to see them emerge as victors.
That the club's official website on Wednesday dedicated over three minutes of footage of every touch from the ex-Porto man at Villarreal is indicative of just how impressive his 45-minute cameo was.
Robertson added: "Hopefully he will only get better. With a full pre-season under his belt I believe he will get better, which is scary, but what he has produced in the here and now is pretty special as well."
Such has been Diaz's impact and how little time he has needed to make it that has now played more matches for club and country this campaign than any other professional footballer in world football. It would have been easy for Klopp to have left his £50m winger out at times, but his 21 appearances have contributed to a whopping 64 matches for Porto, Liverpool and Colombia. That number will likely reach 70 by the time the final whistle blows in Paris.
“Each game is a revenge for always going out to look for more," he says. "I know what it costs and I have to take advantage of every moment, every minute I have. The rest is very important for what is to come. When we reach an instance of these, like a final, what has already happened is erased.
“We know what a final is, in a final you forget fatigue, you play, you run and you fight.”
The chance to strut his stuff in the biggest game in club football is Diaz's reward for his contribution so far and there won't be many betting against him doing just that in the Stade de France on May 28 - whoever Liverpool meet.
