Chelsea have struggled since Todd Boehly took ownership of the club.
Chelsea managed to finish in sixth place this term, after finishing 10th last season.
However, former Chelsea forward Salomon Kalou believes Chelsea will get back to the top.
Kalou insists Chelsea are a big club, and it’s only a matter of time for the Stamford Bridge outfit to shine again.
Kalou said: “Of course, they will [get back to the level we competed at]. It goes full circle, every big team goes around in a circle every ten years.
“You see today, big teams like Barcelona are struggling, but they’re going to come back because they’re a big club.
“When you’re a big club, and you establish yourself as a big club, it might take you a couple of years to get back to your level, but you eventually get there.
“I believe Chelsea will get back to their level – they need time. When you’re building something, you’re starting from scratch, so it’s going to be hard to be ready in one, two, three years. You need at least five-ten years, but I believe Chelsea will get back to their level.
“Every team has its identity, that’s for sure. Chelsea’s identity is different now. But, it’s the direction the club took. They need to back the new manager.”
