The 48-year-old coach was full praise for the powerful striker, who in his opinion would be a quality addition to any club in the world
The 25-year-old attacker has refused to commit his future to the Portuguese champions as reports continue to suggest that Chelsea, amongst others, are eager to sign him.
And Dunga, who handed Hulk his first Brazil call-up in 2009, says that he is not surprised with the striker's role in the Selecao in recent matches and in the interest he has garnered from the big clubs in Europe.
"It is hard to find a player with his characteristics: strength, power, he wins almost every one-on-one situation and can also decide a match with his shots from medium and long range," Dunga told O JOGO.
"He is a player that every club wants because he is different from everyone else."
The former Tokyo Verdy ace, who joined Porto in 2008, has a €100 million release clause attached to his contract with the Estadio do Dragao club.
