Roberto Mancini has criticised his Manchester City team after they failed to hold out for the win against Arsenal yesterday.
Joleon Lescott put the Premier League champions ahead in front of their own fans, only for Laurent Koscielny to equalise for the Gunners late on to ensure the points were shared.
That result left City in 7th place having only won two of their opening five league fixtures.
City were forced to act late in the summer transfer window, and bought in the likes of Javi Garcia, Scott Sinclair and Maicon all on deadline day.
Mancini blamed the run of underwhelming results on the short amount of time his new players have had to bed into the team, and says his team need to improve drastically if they are to retain their title.
"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," he said.
He added: "The second year after winning a championship is always difficult and I hope we start to win in our next league game, because we need a win. But we need to improve if we are to do that."
City face three home games in their next four encounters, including their Champions League clash against Borussia Dortmund next month – all of which they will be confident of winning having failed to taste defeat at the Etihad since December 2010.
