Asa, City's first team minus Tevez failed to beat Notts county, would you say they lack quality? At least our second string has the excuse of not being match fit, not playing togther often as well has having a few square pegs. Cup games are different, I don't know why, but they just are.
It doesn't really matter who you are, there will always be a significant drop in quality in the second string, it's pefectly normal.
