Arsenal boss Arsene Wenger is convinced they can match today's opponents Manchester City.
Wenger believes Arsenal have now clawed ground on big-spending City when once they were running free.
He said: "They were ahead of everybody but let's see on Sunday and show it on Sunday. A big win takes problem away. It makes you stronger.
"I believe we don't have to question our potential to do it. What you want is to turn up with the right performance."
