Sarri expects another tough test on Sunday against West Ham.
The Belgium captain has enjoyed an exceptional start to the season once again, with the Blues sat jointly at the top of the Premier League after five rounds.
Belgian playmaker Eden Hazard has been the star man for Chelsea so far this season, scoring a hat-trick in their 4-1 demolition of Cardiff last week to lead the race for the Premier League Golden Boot.

Giroud, 31, limited to substitute appearances before last week, is yet to score for Chelsea this season but already has three assists in the Premier League. 'I know in London there are a lot of them with different teams.
"I'm happy to have a teammate like that, who pushes me to do better", he added. We will try to do the same as the last game.
