Manchester City midfielder Gareth Barry admits they're still adjusting to life in the Champions League.
Barry admits the Premier League champions have been "found out" to some extent on the biggest stage of all.
He said: "We are finding it tough to put our finger on exactly why it has been tough.
"It is clear we've not produced our best against the quality of opposition in the Champions League.
"My reason is that we have not performed to the best of our abilities and we have been found out."
