An emotional Javier Mascherano said he felt "immense pain" after losing the World Cup final against Germany.
Mario Gotze struck in the 113th minute to give Germany a 1-0 win over Argentina in Sunday's final at the Maracana.
Mascherano was proud to have made it to the final, but he admitted losing in such a dramatic way was hard to take.
"The pain is immense," the Argentina vice-captain said with tears in his eyes. "We wanted to win this for the people of Argentina, for those who came here to support us, but we lost.
"We have represented our country the best we could though.
"We have to lift our heads despite the pain. We gave everything we could out there."
Gonzalo Higuain missed a good chance in the first half and Lionel Messi spurned a similar opportunity after the break.
Substitute Rodrigo Palacio put a header over when clean through in extra-time.
Mascherano wishes his team-mates had put their chances away.
"We had the best chances but we didn't take them," the Barcelona midfielder said.
"And we only had to last another five minutes at the end. We just didn't have that little bit of luck that you need in a final."
