With Roberto Mancini's men also on the brink of another early elimination from the UEFA Champions League, it has been an underwhelming start for a team that promised to kick on.
"The start of the season is completely different to what we experienced last year - not getting out of the blocks and not getting going," said Barry.
"But I think this season is what being champions is all about. You're going to find it tougher and the games will be harder. People want to beat you that little bit more, as we're finding out."
