FC Copenhagen goalkeeper Kamil Grabara says a lack of experience cost them in their Champions League defeat to FC Copenhagen.
City won 3-1 at the Parken in the first-leg of their Champions League round 16 tie.
Grabara said: "We all knew it would be difficult, which it was. We were very naive at the start of the match.
City's second goal came in first-half stoppage time, while the third was scored by Phil Foden shortly before the final whistle.
It was completely unnecessary, believes the FCK keeper.
"It's a shame that we don't give ourselves better chances.
"I did my best to keep the team in the game.
"The last goal was completely unnecessary..."
