The Ivorian has played up the importance of the defending champions' match against Arsenal and admitted that Roberto Mancini's team "have some questions to answer"Manchester City midfielder Yaya Toure believes that the defending Premier League champions must not drop a single point at the Etihad Stadium in order to ensure that they retain the league title.
The 29-year old has helped his side win both of their opening home games this season and hopes to extend that record when they face Arsenal on Sunday.
City dropped just two points on their own turf as they claimed their first championship since the 1967-68 season in 2011-12.
"For us to be successful we need to win at home," Toure told the Daily Star Sunday. "A championship team needs to be invincible in its own stadium and that is the challenge - zero points dropped in an entire season.

"It's a big game for us because we have some questions to answer. We need to show we are better than them and take three points away from one of our title rivals."
The Ivory Coast international went on to praise the new signings that have helped Arsenal make a positive start to the new season despite the departures of Robin van Persie and Alex Song.
"Van Persie and Song were important players for Arsenal but I believe the reinforcements they brought in this summer have made up for them going," he opined.
"Now they are more compact, more solid and they don't depend exclusively on Van Persie for goals. I have seen a lot of [Olivier] Giroud and he has a lot of quality. But I'm going to make sure he has no luck in front of goal in this game."
