Rui Costa still wants Benfica return
The gifted attacking midfielder started his career at Estadio Da Luz in the early 1990s, before embarking on a successful career in Italy with Fiorentina and more recently Milan.
Rui Costa has stated his intention to win trophies with Milan, but claimed it would be an honour to have a final crack at winning the Portuguese championship with his former club.
Benfica are reportedly targeting a summer swoop for Rui Costa, and the player is flattered by such talk.
"I was filled with surprise," he said. "But I do not have any indication of any possible return at the moment.
"At this moment we are talking about mere possibilities which, I have always said, is something that interests me.
"It could happen in one, two or three years, I don't know, but it will be an honour to fulfil the promise I made to finish my career with Benfica."
Commenting on the rest of this season with Milan, he told Portuguese daily, Record: "We are fighting for the championship and Champions League and this is what I am concentrating on at the moment."
