The Gunners travel to Stamford Bridge for their crucial Premier League title showdown tomorrow (12.30pm).
And victory for Chelsea would all-but end Arsenal’s hopes of being crowned champions for another year.
The Blues lead the way by nine points heading into the weekend, following Tuesday’s 1-1 draw at Liverpool.
Antonio Conte has his side organised in their 3-4-3 set-up, which has proven to be effective breaking forward.
Marcel Desailly believes his former club Chelsea will punish Arsenal tomorrow
Chelsea has this capacity to really control the game
Only Arsenal and Liverpool have scored more league goals this season, and Desailly points to the hosts’ ability to punish teams as key ahead of the London derby.
"Arsenal is having a problem because they have possession of the ball all the time but they don't make the difference," Desailly told FourFourTwo.
"When you are facing Chelsea you are have a problem because Chelsea has this capacity to really control the game, handle the pressure the opponent will put on them and have a great transition from defence to make the difference up front with Diego Costa.”

Arsenal's poor performance against Watford on Tuesday could prove costly at Chelsea
While the Blues will be buoyed following their decent result at Anfield, Arsene Wenger’s men are looking to bounce back from Tuesday’s shock 2-1 defeat at home to Watford.
On the teams’ preparations, Desailly added: "If you lose against Watford it is difficult to get the state of mind for winning to straight away compete against Chelsea.
"For Chelsea it is not crucial, you prepare for the game normally. Yes it's an important game, a derby, but it is not something crucial for Chelsea, winning and losing.
"The important thing is to have consistency throughout the rest of the season. Then you are sure to win the league in that case."
