Hernandez impressed in United's Community Shield victory over Chelsea on Sunday.
"I think he can handle that (hype)," Ferguson told MUTV. "He's got a nice personality and nice manners, he speaks the language well and he's integrated into the first team squad very well. The players love him. His goal today, it was going in anyway, but fortuitously it hit his head and it counts as a header! It was unbelievable."
