No we beat those level, like we did vs Basel or Schalke under Pep. (Knockout rounds.)
But if in last 16/last 8 we face Inter, Lazio, Leipzig, good clubs but we cannot compare how much City squad is stronger there we will have issues as they can hurt bigger teams on any day and if our tactics are as shit as it was in Spurs away, Lyon game recent years we will lose.
I prefer to only lose to later winner, that is the only acceptable form of going out in CL away to a team that is as good as they can go and win it. Did not happen under Pep yet. Or lose to an extremely strong squad in a very close tie, that also did not happen with Pep yet.
