Mourinho became genuinely concerned about his training-ground attitude in the USA last summer, and who was dropped for the Champions League game with Schalke after missing a session at Cobham.
The penny, unquestionably, has dropped.
Mourinho said: "He understood that he was wrong, but was wrong in a naive way. I remember perfectly that in that game he was in the dressing room with the team, he was behind the dugout, even if he was not selected. He accepted immediately.
"This was an episode, an isolated episode, because the reality is that since the pre-season, once he understood the levels of professionalism I demand from my players day by day, he's worked hard to try to be the best possible."
