Juventus winger Emanuele Giaccherini had admitted his new team are yet to reach their full potential and that Milan could be an important marker.
The diminutive wide-man signed from Cesena over the summer and has played in three of the team's four games under Antonio Conte.
Whilst the team are top of the League on goals scored, the 26-year-old believes the team are yet to reach their expected levels.
"We're top of the table and we need to continue in the same way, but we know that there's still room for improvement.
"This team hasn't shown all its potential yet. The squad includes champions who will allow us to make a great step up in quality. The game against Milan will be the first important test of the season and on Sunday night we'll have more of an idea about where we are."
