Don't they state that Sakura confessed to Naruto to try and get him to give up on Sasuke? I think her intention was to get Naruto to let go of his idea that he could save Sasuke.

I think KISHIMOTO is writing Sakura in love with Sasuke, because I doubt he has the subtlety to comprehend of a woman loving a man she isn't related to that strongly in a platonic way. That said, I don't think fanwriters need to write Sakura in love with Sasuke.
