The full Man City squad played on the match day against Liverpool and they could not do anything, talk more of now that key player like Walker would be missing in the match. What do you think would happen. Don't also forget that Arsenal won Liverpool that almost win City on that day, because they had more chances of scoring than City.
Comparing Manchester City Vs Liverpool and Manchester city Vs Arsenal isn't right because this two games are very different games. When Manchester city plays with Liverpool, this is a big game that demand big moments for any of the team to win because both teams play very well like their life depends on the match. Manchester city Vs Liverpool is a derby of some form because both teams have a rivalry between them but when Manchester city plays Arsenal, it'll like a big team playing an average team but until recently that Arsenal began to pick form and now playing very well in the premier league. Matches between Manchester city and Arsenal don't have draws and that isn't how a big game statistics should be because if they were two big teams playing they should have some draw games in recent meetings but there isn't.
