Esteban Cambiasso says Inter Milan's players are responding to coach Water Mazzarri's methods.
Inter impressed for their 1-1 draw with Juventus on Saturday.
“Mazzarri has taught us so many concepts, but we have managed to get to grips with them quite quickly,” the midfielder told Area.
“We have rediscovered some self confidence because we believe in what we are doing. Not just in games, but especially in the work we do during the week.
“If that wasn’t the case then we wouldn’t have put in the performance we did against Juventus.”
