The 25-year-old forward added to his goal in a pre-tournament friendly against England by scoring three times in Brazil, but Ecuador exited at the group stages.
Valencia, who only left his home country to join Mexican side Pachuca in January, feels that he has done enough to earn a switch to Europe in the near future, with Everton, Tottenham Hotspur and Spanish side Espanyol all believed to be tracking his progress.
He told TV Azteca "It would be a good moment to move to Europe, after what I have done in Mexico and at the World Cup.
"I really like Italian football but if this jump to Europe happens, I will welcome it and try to do my best wherever I go."
Pressed on reported interest from La Liga, he added: "These are the best leagues in the world. If there is an opportunity to move to one of them, you have to do it."
Valencia has netted 18 goals in 23 appearances for Pachua since signing from Ecuadorian side Emelec.
