Sergio Aguero and Lionel Messi have known each other since they were children so it is fair to say you can take the Manchester City striker's word for it when he said his close friend was in a bad way on Sunday night.
Argentina was left in a state of proverbial mourning after their national team lost their third major final in as many years against Chile in the Copa America final.
In a repeat of the 2015 tournament, the two South American juggernauts played out a 0-0 draw before Alexis Sanchez and co. achieved a historic double on penalties, winning 4-2.

Having also lost in the 2014 World Cup final to Germany, it was too much to take for some in the team and no more than their talisman Messi, who missed the first of Argentina's spot-kicks.
Aguero has confirmed that it was Messi who looked the most devastated in the dressing room following the conclusion of the match, claiming it was the "worst I have ever seen him".
"We are all s****y, we are trying to think about other things and continue on forward," said Aguero, according to The Mirror. "But it's hard. Once again luck has gone against us.
"Unfortunately, the most broken one is Messi for his missed penalty. It is the worst I have ever seen him in the dressing rooms after a game."
Not only did the five-time Ballon d'Or winner burst into tears, he also appeared to announce his retirement from international football. However, Messi was hardly definitive with his words and did appear to allow a lot of room to renege.
He said: "It's tough, it's not the time for analysis," Messi said. "In the dressing room I thought that this is the end for me with the national team, it's not for me.
"That's the way I feel right now, it's a huge sadness once again and I missed the penalty that was so important. I tried so hard to be a champion with Argentina. But it didn't happen. I couldn't do it."
World Cup 2018
Attention will now turn to whether Messi could really let his international team-mates head into the next World Cup while he sits at home. He will turn 31-years-old that same summer, and it would surely represent his final chance to lift the coveted golden trophy.
Argentina's goalkeeper Sergio Romero has already suggested that Messi's words were said in the heat of the moment and expects the country's all-time top scorer to return for the tournament in Russia.
"I think Leo spoke in the heat of the moment because we missed that great chance," said Romero.
"I can't imagine a national team without Messi. I think he'll reflect [on the decision]."
