Nervous excitement and rowdy cheers turned into anguished groans, nailbiting tension and tears, as Argentines' hope of yet another epic comeback led by Lionel Messi in the World Cup fizzled out against Spain.

At the Cafe Relax bar in the historic center of Buenos Aires, fans with tears in their eyes after the final whistle blew on the 1-0 defeat said that what saddened them most was that it was almost certainly 39-year-old Messi's last shot at a World Cup.

"I feel empty. Empty because of Messi, because I won't see him in a World Cup again. This is the last one," said Camilo Cichero, a 22-year-old architecture student who was comforting his crying friend.

"It's not how we expected it to go. At least it gives me peace of mind knowing he's already won everything there was to win."

Composing himself, his friend Juan Saenz, 22, a law student said: "This was the last of Messi ...it was the very end, and it finished this way."
