Sure, the pressure was there to a degree against City but with so many games left and no expection in terms of being the outright leader because of the time left in the season, it wasn't absolutely crucial to win. There were plenty more clashes against 'rivals' to prove our mettle in that regard. It was really just another of the small steps. The last dozen games are when the pressure really cranks up and the last two games have illustrated that when the intensity increases even further, the squad isn't prepared enough to cope. It has happened too many times over the past 5/6 years for it not to be an insurmountable problem for Wenger. He is good at working with players high on confidence - hence the long stretches of form at times - but he cannot find it within himself to dig them out of a hole when shit hits the fan.
