There has been talk this week of bust-up between the pair.
"I honestly do not understand where this has come from," Antonio Ottaiano told ArenaNapoli.
"There may have been something between the Coach and the player during the game, but that was just to give advice.
"It's a completely normal thing. Lorenzo, as always, does what the Coach wants him to.
"Napoli are a highly competitive team, and can only field 11 players. There is nothing abnormal about that."
