Arsenal boss Arsene Wenger says he aware of the threat posed by Chelsea's Diego Costa, Willian and Eden Hazard ahead of tomorrow's game at the Emirates.
The Gunners host the Blues hoping to keep the unbeaten run started against Watford intact.
The two teams are fourth in the table on ten points with Manchester City leading the pack after five wins out of five.
"It is an important game for us because we feel we are on the way up and Chelsea is a good test and a good opportunity for us to continue our progress," Wenger explained.
"Chelsea in the last 10 years had very, very strong teams. You realise that today as well. Before that period, we were always beating them, after they were always the stronger team for a few years.
"Now, it looks like it's a new era where it's a bit more balanced again and we feel we are progressing at the moment so we have a good opportunity to grab and to change what I call 'the inconvenient facts' of the recent years.
"Chelsea have always come to the Emirates with a strong defensive solidity and to [try to] catch us on the break, because they know we like to take the initiative," added Wenger.
"[Antonio] Conte has very strong players in transition, like Hazard, like Willian, like Diego Costa. For us to stop them, these three players, from being dangerous will be one of the keys of the game."
