Teodoro Fonseca says the Brazilian has outgrown the Portuguese league.
"Porto are a big club, has a great structure and a high ranking in Europe. The problem is the Portuguese league ... Hulk has been champion in everything there except the Champions League, won by Chelsea. He has the dream of winning the Champions League and asserting himself in the national team.
"For now he will have to take a leap into a more competitive league and he admires greatly the Premier League."
