The Blues currently have six players with the Dutch club which has attracted criticism from clubs in Europe who feel there should only be three overseas players on loan at any one club.
"For young players, the ages of 18 to 21 are the most difficult time. We felt it is better for them to go on loan to somewhere where they get good competition," said Emenalo.
"It's working with Vitesse because the Dutch league plays in a desirable way and they have done what they promised. When they say they want a player, the player actually does play.
"If tomorrow a Championship team in England wants the same kind of relationship with us it is no problem.
"We don't send players out because we are trying to recover money. We send them because we want them to play and develop, and monitor them."
