Manchester United winger Nani admitted it was a "special feeling" as he helped defeat his old team Sporting Lisbon 1-0 last night.
"It is a very special feeling, it was here that I played great games and I developed. It was very good to come back and see this stadium full, with two teams who play good football," said Nani.
"When I knew that I was starting, I felt a little nervous, as any player would who returns to face their first team.
"I was confident that when I and Cristiano Ronaldo entered the field for the first time we would be applauded, but also that as the game went on, we would be booed. It is normal, this is football."
