Arsene Wenger has conceded that his side suffered from a 'mental block' that they were able to clear after beating Chelsea in the Community Shield before this current campaign.
Arsenal had never beaten Jose Mourinho's Chelsea before the 1-0 victory at Wembley stadium last month, and go into the showdown six points ahead of their London rivals.
That win - Wenger's first in 13 attempts against Mourinho - has bolstered the Frenchman's confidence and he believes his side can claim all three points, but he conceded that the Gunners struggled when going up against Chelsea in the past.
“It can sometimes be a mental block for the players or a team when they do not beat a team,” he told reporters. “So on that front it was good to win the Community Shield.”
He continued: “It is a big game. But let’s not forget it is the start of the season. What matters on the day is the performance. We know our position at the end of the season will depend on how we do in the big games.”
Arsenal go into the game on the back of a convincing 2-0 victory against Stoke, while Chelsea have won just one league game so far and stumbled to a 3-1 defeat against Everton last weekend.
However the Gunners suffered a surprise defeat in the Champions League in mid-week while Chelsea bagged a morale-boosting 4-0 victory over Maccabi Tel Aviv - and Mourinho believes that's just what his side needed going into the showdown at Stamford Bridge.
We come with a different feeling. We can wake up with a different state of mind," he said. "Saturday is a big match, it's a great rival. This result can put us in a better situation."
Wenger meanwhile refused to be drawn on the subject of his tetchy relationship with Mourinho. The pair refused to shake hands last season and the Community Shield.
The Arsenal boss said when asked about shaking hands: “I don’t want to talk about that.”
When pressed he added: “I won’t tell you more that I just told you. I have nothing more to say about this situation.”
Can Arsenal make it two wins in a row against Chelsea?
