Ilkay Gundogan has talked of his pride at representing Germany at the World Cup, but admits that his side's campaign was a failure.

The defending champions were dumped out of the competition at the first stage for the first time since 1938, claiming just three points from their three matches to finish bottom of Group F.

Manchester City midfielder Gundogan, who was at the centre of a media storm ahead of the tournament, admits that he is still feeling the pain of Germany's early exit and hopes to quickly respond.

"We are all still so disappointed. We had big plans, but we failed," he posted on Twitter. "I'm proud to have played for the 1st time for #GER at a World Cup, but to exit in the group stage is nothing but frustrating. We have to get up again for the challenges after the summer break - and we will."

Gundogan featured in just one game in Russia, playing an hour in the 2-1 win against Sweden.
