Alves threw a strop at being substituted during their Champions League win at Manchester City this week.
"Dani is one of the nicest, most talkative, guys in the dressing room, with a competitive spirit," said Enrique.
"I already knew him as a player, and now from a closer distance I can say that he's an example of what a professional should be. What happened is normal, it always happens. Every footballer always wants to play. Some show it one way, others in a different way."
