Arsenal defender Per Mertesacker says they're up for their clash with Chelsea on Sunday.
The Gunners go to Chelsea on the back of their Champions League rout of Galatasaray.
"Obviously (it is a) good lift (before the Chelsea game). We have got good confidence at the moment and will try to implement that into the game on Sunday," Mertesacker told Arsenal Player.
"We know we can do better than the two consecutive seasons (at Chelsea) before and I think we will try new things on Sunday to get a better result than last year."
