Nana Kwaku Bonsam -- whose name translates to "Devil of Wednesday" -- said in a interview with Kumasi-based Angel FM that he knows about Ronaldo's injury and he is "working on him."
It was confirmed Wednesday that Ronaldo has tendinosis in his left knee and a muscle problem in his left thigh, which resulted in him missing the 0-0 draw with Greece. Ghana is set to face Portugal in their final match in Group G at the World Cup. The group also includes the U.S. and Germany.
"I said it four months ago that I will work on Cristiano Ronaldo seriously and rule him out of the World Cup or at least prevent him from playing against Ghana and the best thing I can do is to keep him out through injury," he said, according to the Guardian.
He is very determined and said he will continue working until he takes Ronaldo out of the running.
"This injury can never be cured by any medic, they can never see what is causing the injury because it is spiritual. Today, it is his knee, tomorrow it is his thigh, next day it is something else."
