Sporting Lisbon coach Paulo Bento says it will be a great occasion to face the club's former stars Cristiano Ronaldo and Nani, now of Manchester United.
"Those two players are leaders in Portuguese football and have helped Sporting's finances," said Paolo Bento. "Although Manchester United have a lot more than us, they are human, just like ourselves.
"Sporting will show respect to Manchester United, just as we expect them to respect us."
