Selby said: “Ronnie has been on a phenomenal streak in the couple of months before Christmas and has got himself back up to No2.
“I think I have got potentially more money coming off than Ronnie in the coming months, though I could win those tournaments again.
“I think he would have to win the world title to do it, but it is possible.
“When his head is right he is still the best player in the world for me.”
