"When we're back from the national team, we have the very tight schedule of games," said Ivanovic.
"I think we have to work very hard to be top, and use all the squad for these kind of games that are coming up for us.
"I think we are (heading) in the right way."
Ivanovic insists the Blues must pick up points when they are not playing well.
"This year is going to be a very tough, a very difficult league," said the Serbia defender.
"Every team will have a bad period and a good period. The important thing is in the bad period to take the points, and to stay (in contention).
"Arsenal are doing well at the moment, but the season is a long one."
