Manchester City midfielder Ilkay Gundogan believes the club can only truly cement themselves as an elite side by winning the UEFA Champions League.
The German spoke ahead of City's clash with Real Madrid in the last 16 of the competition on Wednesday.
Per Goal's Jonathan Smith, he said:
"The Champions League is maybe the most prestigious competition in the game, and if you don't win it, as much as we are a great team, you feel like there's always something missing.
"Obviously, we try to do our best, but it's not something that you can talk about and then it comes.
