The Argentine is about to accept the contract of a lifetime in China after two years at Fluminense
Guangzhou Evergrande are currently leading the Chinese Super League and are looking to strengthen their squad in a bid to push for glory.
Conca, 28, signed for Fluminense in 2009 after a season on loan at the club and has been a big hit in Brazil.
Globoesporte reports the Argentine has been offered €26.5 million for a two-and-a-half-year deal, which will see him earn approximately €10.4m a year.
This deal will be put him near the game's top earners, only behind Real Madrid's Cristiano Ronaldo and Barcelona's Lionel Messi, according to a list published by France Football in May.
Fluminense coach Abel Braga stated this is an amazing opportunity for the player and confessed he should accept it.
"This is a good offer for the club and perhaps adjectives will not be able to describe what it represents to Conca. It will allow his independence and that of his family in two and a half years," he said.
"This offer will put him in the list of the top 10 highest-paid players in the world. Let us wish for it to happen. He is a guy [who is] completely identified with the club and it will be a unique opportunity."
