The 27-year-old was frustrated by his side's inability to finish chances, while also pointing to the fact it had a day less to recover for the final.Lionel Messi blamed Argentina's 1-0 World Cup final defeat to Germany on the team's forwards for being wasteful in front of goal.
The 27-year-old was a peripheral figure on the night and fired wide a golden opportunity to give his side the lead in the second half after Gonzalo Higuain had done the same in the opening period, while Rodrigo Palacio also scuppered a great chance.
Argentina was then punished for its failure to convert those chances when Mario Gotze scored a brilliant winner in extra time to take the World Cup back to Germany.
And Messi believes his side deserved better, insisting they should have taken their chances.
"We haven't been in the semifinals for many years and the fact that we played the final and the way we played it it's something to be proud of," Messi said after the game. "But we deserved more and that's why we are sad. The strikers missed the chances we had. It's a bad feeling for all of us because we couldn't win the cup and take it to our people."
Argentina made it to the final after beating the Netherlands on penalties in their semifinal on Wednesday, a day after Germany thrashed Brazil 7-1 in their last-four clash.
And Messi felt the ease at which Joachim Low's side cruised to victory last week, along with the additional 24 hours of rest ahead of the final, was key as the final went into extra time.
"I was OK physically as were the rest of us," he added. "The fact that we played a day after them and that we played extra time against a team that was able to rest in the last minutes of their semifinals affected our finish of the game. A difference of one day is big at this stage."
Messi could take one small crumb of comfort from his evening after being awarded the Golden Ball as the best player of the tournament, though he said the prize "meant very little" on a disappointing night.
