The 21-year old Italian striker, currently on loan with Espanyol, says he would like to make his way to England once he further develops his game.
"Football is strange, but I have great confidence in my ability and I know that I should," he said.
"For the future, I dream of playing in the Premier League."
However, Longo said for now he is content at Espanyol and could even spend another season in Spain.
"I'd be happy for another year," he said.
"We'll see what will happen, but I think at the moment only about playing and continuing to fight for a starting spot.
"I do not know about any Inter regrets, I only know that for the moment I am very happy here at Espanyol."
