Martinez's men face a stern test as unbeaten City visit the DW Stadium but the Spaniard - who oversaw dramatic late-season wins over Manchester United and Arsenal to avoid relegation last term - is confident of troubling the champions.
He said: "I think from a tactical point of view you have to be perfect. The moment you make a mistake you are going to get punished.
"From every other angle of the performance I do think we can compete against anyone in the league.
"Physically and technically I think we are ready. On the day, tactically, we will have to be perfect but we have done that in the past. We have done it many times and not long ago.
"That is really fresh for us to be able to enjoy the occasion and the challenge and take responsibility.
"I want ourselves to be the ones taking the responsibility, playing at home, and try to dictate and look for a win from the start."
