Germany have been sent home early after their shock penalty defeat to Paraguay in the round of 32 on Tuesday (June 30).
Neuer, 40, made the decision to come out of retirement to once again represent his country, but failed to have the desired impact.
Despite Germany’s early exit, Neuer insists he made the correct decision, expressing his pride of playing in a fourth World Cup.
Neuer wrote on Instagram: "It has always been an honour! The early exit from the World Cup is extremely disappointing.
“We clearly fell short of expectations and should have progressed further in this tournament. This ending is very painful.
“I made a conscious decision to play for Germany one more time. Firstly, because wearing the national team jersey has always filled me with deep pride."
"Secondly, because at 40 years old and with the experience of four World Cup tournaments, I wanted to support the young players both on and off the pitch in the best way possible and help German football.
"Despite the bitter end, I don't regret this decision for a second. My disappointment is indescribable, yet I feel immense gratitude.
"Thank you for your support over all these years and during this tournament."
