In your eyes maybe.
Ancelotti has already said Casillas would have to earn his place in the team. Lopez has done NOTHING to be dropped. You aren't going to drop a superb keeper in Lopez just because Casillas is a fan favourite, that'd be disrespectful to Lopez as a person and a footballer, you don't want that. Ancelotti showed respect to Casillas by playing him in cup games, with him in goal they won copa del Rey and Champions League.
ok but that's different to what you were saying earlier. If Ancelotti thought Casillas was a better keeper then he would be first choice in the league. He obviously doesn't so he isn't.
