Chivu has admitted that he's concerned with the way his struggling Inter side are playing right now.
"The worry at the moment is that we're not playing good football," he told Sky Sport Italia. "So that's what we're working on, mentally and physically.
"Boss Andrea Stramaccioni? I think his main concern is getting on with the job," the defender commented as uncertainty grows over the Coach's future.
"I'm sure everyone realises that he's done everything possible, but we all know that the Coach is the first one to take the fall, followed by the players and so on.
"There's only one way out of this and that's through hard graft."
