Ferdinand has told top players round the world that if David Moyes wants to sign them they should seize the chance of going to Old Trafford.
He told The Sun: “If United come in for you, you take it.
“Even if you are a great player you become a better one at this club. Cristiano Ronaldo became the best player in the world having come from Sporting Lisbon.
“We are well paid, of course, but it’s more important for me to be at a club which enjoys success, and historically is the greatest in the world, than to earn a bit extra somewhere else.
“I could have left United for more money but that’s never stimulated me. I’ve had the greatest stage here.
“If you have ambition your aim has to be to make a name for yourself at a top club. Money should not be the over-riding factor.
“As a player aged between say 23 and 27 that is what you should be looking at. It shows you are going somewhere and want to win trophies.”
