Arsene Wenger accepts it is time for Arsenal to address their reputation as a soft touch against their main rivals.
The Gunners' record when facing Chelsea and Manchester United is abysmal, losing 14 of their 18 encounters since 2007 and registering only two victories.
Chelsea visit Emirates Stadium on Monday night hoping to secure a sixth successive victory over their London rivals having scored 13 goals in their previous five games.
"Of course we have a point to prove given our record against the big teams," said Wenger.
"You have to show that you are up to the level expected from you in these games.
"That's the obstacle to get over. At home in the big games, you want to win.
"We don't really think about the record because the statistics are history and every game is a new start.
"Every player has lost a game before he has won one. One day, he wins. We have to make sure for us that day is on Monday.
"Our statistics recently are against us because we have a very young team.
"But three years ago, we lost the small games and didn't lose the big games but still lost the championship so we have to combine both sides of it.
"We are in a strong position now and we know our home form against the big teams will be the decider for the championship."
