Chelsea are currently on a five-match winning run in all competitions, most recently seeing off Gent 4-2 in their Conference League opener on Thursday.
However, Maresca has insisted people should not get carried away by Chelsea’s recent form, playing down their chances of lifting any silverware this campaign.
“I really don’t think we can compete with City or Arsenal,” Maresca said.
“I really don’t think that, because we are not ready. The reason is that City has worked with the same manager for nine years and Arsenal for five years. If you want to compete for big things, you need that time.
“After Arsenal beat PSG [in the Champions League] they asked Luis Enrique, and he said the same thing, that Arsenal have had the same manager for five years and [PSG] only a year and a half.
“Imagine us, only three months… so it’s a huge difference. So, I am really convinced we cannot compete with those clubs.”
Before Maresca’s appointment, Mauricio Pochettino only spent a season at Stamford Bridge, while Graham Potter before him was only in the position for just under seven months.
