Our Head Coach believes our first London derby of the season and biggest Premiership game under his charge so far will provide a platform to see just how far we've come.
Still unbeaten and currently sixth after five games, we travel to Stamford Bridge to face a Blues outfit sitting second with four wins and a draw in five league outings and just one goal conceded.
"It is very important for my players and me to play one of the favourites for the championship because the players and I can see our progression from the first game against Liverpool," said Jacques.
"Chelsea, with all their players, are aiming for the title. We hope for a good result but the most important thing is the progress for our organisation, for the team and each player because a lot of players are very young and have only four or five games in the Premiership.
"Last year I saw many Chelsea games because of Gallas, Desailly and Makelele. I know many players have left Chelsea but the players that stayed and the new players, like Didier Drogba who played in the French Championship last year, I know them well.
"I know the coach Jose Mourinho as well. I sat next to him at last season's Champions League semi-final between Chelsea and Monaco.
"In the last four years he has won the Portuguese Championship, the UEFA Cup and the big competition, the Champions League."
Jacques Santini is relishing the prospect of taking his new-look side to Chelsea on Sunday.
