Obviously he knew that getting in to the Uchiha compound and getting to Izuna were going to be two different tasks with two very different levels of difficulty. For a sensor of his ability it wasn 't all that hard to avoid the patrols and find a spot where he could slip between the buildings out of sight, feet silent as they tread on cursed ground. Much harder was dodging the rapidfire attacks of an overprotective maniac. He 'd forgotten that Madara was a sensor too, not quite as naturally talented as himself but well trained and quite sensitive.
