Sounds like a load of nonsense to me.
It's not as if he was picked up off the streets and sold as a footballer when he had never kicked a ball in his life.
He was playing in a professional league, a league that has some excellent teams in it. He scored goals in this league. Everton had the opportunity to scout him and I am sure they did. They were not forced to buy the player they chose to do so and agreed the price.
Are people suggesting that we have a scenario similar to the " Gay Future " situation of a number of years ago. Did somebody deliberately paint over the blaze running down his forehead to make him look like a different footballer.
The fraud thing just doesn't seem plausible.
