Everton boss Roberto Martinez believes clubs now know they can send their best youngsters on-loan to Goodison Park without concern.
Martinez said: "Clubs have seen the other loanees and how well they have been looked after.
"We have had phone calls from clubs asking about taking their players for next season. They see it as a perfect step-up in their career.
"Put yourself as a director of football. You spend £20million on a youngster, but there is no place for him in your team yet.
"You aren't going to send him somewhere that he is not going to develop or to a club with a different style."
