It was put to Mourinho on his arrival in Jakarta, where Chelsea on Thursday play an All-Star XI, that his compliments towards Moyes were a calculated act designed to destabilise the Premier League champions.
Mourinho said: "If to say that my colleague in Man United is a great coach, he deserves success, he deserves time to work, he didn't win trophies at Everton because it's difficult to win trophies there. If to speak good about him is to play mind games, what do you say if I speak bad about him?
"The best thing is not to speak, and if I don't speak nobody says nothing."
Like Moyes, Mourinho believes it is better to sign players early in the transfer window.
But, unlike United, Chelsea have already recruited Andre Schurrle, Marco van Ginkel and Mark Schwarzer this summer.
"He's right," Mourinho said. "The sooner you have the players, the better.
"You know the squad you have, you know what you have to work with, you have time for that."
