Juventus coach Max Allegri says victory over Inter Milan will be crucial in their title defence.

Juve meet Inter later today.

“Small incidents eventually become fundamental, which is why we must realise every detail matters and it'll be much more difficult to win the Scudetto. Just because Juventus have a stronger squad doesn't automatically mean we will win every game," said Allegri.

“Tomorrow is a fascinating game, the Derby d'Italia, it is the first stepping stone to the Scudetto. Some wonder it's only the fourth week, but I tell you it IS the first stepping stone to the Scudetto.

“There are three or four games in a season that you feel can be decisive at the end of the day and this against a strong Inter side is one of them.

“Everyone is available, Stefano Sturaro will be from next week because today he's playing for the Primavera youth team. The only one certain to start tomorrow is Stephan Lichtsteiner – him against everyone! OK, Sami Khedira will play too.

“There will be changes, we have a series of games in the space of three days, so yes I will need everyone. Let's also remember that the bench is not an insult, it is a choice by the Coach, and at the end of the season the winning team is the one with the strongest bench.

“In March when you lack the players to come off the bench and win you games, it becomes a problem winning the Scudetto."
