Manchester City striker Edin Dzeko is upbeat going into their clash with Arsenal.
Dzeko is expected to start for City this weekend against the Gunners.
"It will be difficult, but I'm an optimist," Dzeko declared to City's website.
"As with every season, there are several teams that will battle for the title of champions in England.
"This season Chelsea might be the most serious challenger, but we mustn't ignore Liverpool, Tottenham, Arsenal, or United, who will certainly be much stronger than last year.
"After all, everyone has gotten stronger, and everyone wants to be first."
