Manchester City manager Manuel Pellegrini has admitted that he was left frustrated by his side's 1-1 draw with Roma in the Champions League.
City took an early lead through Sergio Aguero's penalty, but Francesco Totti hit back for Rudi Garcia's men to become the oldest scorer in Champions League history at the age of 38.
"It was frustrating because we didn't play the way we normally play here at the Etihad," he told Sky Sports News.
"That's why we are concerned that the second we prove a lot, we deserved to score the second goal. I think this team has played three years in the Champions League, they are not [inexperienced].
"Today was not our day. We just go for the next game and try and get the results. We are playing important teams and we'll see at the end which team has the quality to qualify."
City now have just a point from their first two games, and travel to CSKA Moscow next.
