City have crashed out at the group stage in their two previous campaigns.
"The last two seasons, without making excuses, the groups that we've had have been really hard," the defender told Sky Sports News.
"I think this group is still hard but is a little bit easier than the last two.
"We started off with a good win away and we are at home now so hopefully we can get another good result, but it's massive for the club now.
"We won the Premier League, or scraped it by goal difference, and now we want to improve every year and it's important we do that in the Champions League."
