Manchester City boss Roberto Mancini feels his team is still to gel.
Mancini hinted that perhaps the need to integrate new boys Javi Garcia, Scott Sinclair, Maicon, and Matija Nastasic has disrupted the Blues' flow.
Asked if the introduction of new players had been a factor after seeing the Gunners fight back, Mancini said: "It could be this.
"We had new players only in the last two or three days of the market, and maybe these players don't know their team-mates well, and need time."
