The powerful striker's representative thinks that his charge is worth the figure in his release clause and stated that the 25-year-old is one of the best footballers on the planet
The Brazil international has been strongly linked with a new challenge since the summer, with Paris Saint-Germain and Chelsea understood to be his primary suitors.
Porto are holding out for the figure in Hulk's buy-out clause, which would break the world transfer record, surpassing the €94m which Real Madrid splashed out for Cristiano Ronaldo in 2009.
Still, Teodoro Fonseca believes that his client's price-tag is not too high, telling Radio Renascenca: "Hulk is one of the best players in the world and he is being followed by big clubs in Europe.
"One hundred million euros is not such a high figure. Every European club knows that the money spent on him would be compensated by his talent.
"A Chinese club is already paying €10m per annum to an athlete and some Russian clubs are already paying €20m."
