Ollie wrote in the Sunday Mirror: "Ruben Loftus-Cheek will be financially secure for life even if he never kicks a ball in the Chelsea first-team.
"I don’t know young Ruben and I sincerely wish him all the luck in the world as he embarks on his career.
"But what kind of game has football become if clubs are prepared to pay the kind of riches the man in the street can only dream of based on potential, rather than achievement?

"Those kinds of things have become the norm.
"Making players millionaires before the age of 20 is, in my opinion, morally and ethically wrong."
