Douglas Maicon admits the appointment of Leonardo has turned Inter Milan's season around.
Leonardo so far has a 100 per cent record since his arrival.
"Since Leonardo arrived, things have changed a lot around here. The atmosphere's great," Maicon told FIFA.com.
"He's been able to get his ideas across already, despite not being here long, and everyone has grasped what he's said.
"It's not just me, everyone feels more motivated since he's come in. We're all in it together and we're going to do our best to help him do a good job."
