Arsenal defeated Chelsea in the last two meetings in the Community Shield and the FA Cup and Petr Cech wants the Gunners to use it to their advantage when the two teams face each other in the league clash at Stamford Bridge on 17 September.
The north London club's last two silverware came at the expense of the Premier League winners. However, Arsene Wenger has seen his side struggle in the league as they suffered two defeats at the hands of Stoke City and Liverpool.
Against Mark Hughes' side, Arsenal created a lot of chances, but were unsuccessful in converting them. However, they suffered a crushing 4-0 loss at the hands of Liverpool and Wenger admitted that "everything" was wrong with the Gunners' performance at Anfield.
Cech claims Arsenal's defeat to Liverpool was like a "big slap in the face" and he wants the Emirates outfit to clinch a win against a big side to prove his side's title credentials.
"We have to draw a line under what happened and move forward. We played Chelsea in the Community Shield and in the FA Cup final last season, so we know we can beat them," Cech told Sky Sports.
"They know they lost two games against us that they were not happy to lose, so this is something we have to use to our advantage."
"The games we played at Stoke and Liverpool didn't go the way we wanted. The performance at Stoke was much better than the result, because we had enough chances and opportunities, but we couldn't find the final pass or finish moves off.
"It was not the result we wanted or expected, and probably deserved. Liverpool was a big slap in the face, it wasn't acceptable for a club the size of Arsenal and the team that we are.
"We had to really make sure we put things right against Bournemouth and the reaction from everyone was brilliant.
"The determination and intensity was there against Bournemouth, the way we played was more like it. Chelsea have the same objective as us, they want to challenge for the title so it's a big game this weekend.
"If we want to be close to the top of the table after two defeats then we have to win the big games and this is the first opportunity for us to do so."
