"Unfortunately the pain will be there for life because this was our chance," said the Barcelona midfielder.

Argentina played extra time in three of their four knockout games and also had a day less to rest ahead of the final than the Germans after squeezing past the Netherlands on penalties in the semi-final on Wednesday.

And the 30-year-old admitted they ran out of steam in the second-half of extra time when Mario Goetze struck the winner seven minutes from time.

"It is difficult to explain. It escaped from us at the last minute, we did everything to try and win. We had the best chances until we ran out of gas.

"The pain is immense because we wanted to take the World Cup back to Argentina but we gave everything. We are empty, we gave what we had and we are sorry for ourselves, for the people that came here and for the people that are in Argentina.

"Football is like this and we have to raise our heads and deal with the pain."
