The Blues boss memorably described the nucleus of his first Chelsea side as permanent names on the team-sheet, but believes his underperforming players are short of that status this term.
"Untouchables in football, only consistency can give you that status," said Mourinho, whose champions are 15th in the Premier League after two wins in the opening seven games.
"You have to be a fantastic player, but you have to be consistent.
"In this moment we have fantastic players, the players that gave us the title last season
But football is about today, it's not about yesterday
In football you have to be consistent in your performance, in your emotion
"To be a winner you don't need to win all the time, but to be a winner you must have a strong mentality every game, every day
At this moment I don't have untouchables."
Chelsea have Diego Costa available for Tuesday night's Champions League Group G clash at Porto, Mourinho's former club, with the striker in the middle of a three-match domestic ban.
Mourinho lauded Costa's performance in the win over Arsenal, when the Brazil-born Spain striker was a nuisance and retrospectively banned for grappling with Laurent Koscielny.
Asked if he would like 11 players to show the same desire of Costa, Mourinho said: "I think we would lose every game because the desire to suspend him is so big that we wouldn't have players to start the game.
"I'm happy to have only one and let him play until they decide to suspend him again."
