The £12.5million Watford record signing has managed just one game this season because of various injury issues and media reports claim that the striker has had “juju” placed on him.
According to AfricanFootball.com, Success is struggling because of dark magic.
A source is said to have told the website: “His people are beginning to think that it is some people who are not happy with his progress who are chasing him with evil witches.
“They are suspecting juju against the boy.”
The former Nigeria youth international arrived as a club record signing in the summer from Granada expecting to form a partnership with Troy Deeney.
But the 21-year-old Nigerian has started just one game and made seven brief appearances off the bench in the Premier League.
