An extra-time strike from Mario Gotze was enough to secure a 1-0 victory over Argentina in the Maracana on Sunday night, and Lahm believes that Joachim Low's side proved that the tournament was not about any one player.
"Whether we have the best individual players or whatever does not matter, you have to have the best team," the 30-year-old told reporters.
"We stepped up time and again in the tournament, did not let ourselves get distracted by any disruption, went on our way, and at the end you stand there as world champions - an unbelievable feeling. The team has remained quiet and patient."
Germany's triumph was the first time a European side has won the trophy in South America.
