Esteban Cambiasso admits there's been big changes in preseason under new Inter Milan coach Walter Mazzarri.
The Argentina international is preparing for his tenth season at Inter.
"We've already seen it. Perhaps not everyone can see it immediately but hopefully it will be clear to everyone soon. Did we not work hard enough or well enough before Mazzarri? The training methods have changed as you expect them to when there's a change of coach. But you should never say anything bad about a coach who's not here anymore," said Cambiasso.
