Man Utd v Sporting
Cristiano Ronaldo and Nani have been named in Manchester United's line-up to face their former club Sporting Libson.
John O'Shea, Darren Fletcher and keeper Tomasz Kuszczak will also play, while defender Nemanja Vidic could replace Gerard Pique after a back problem.
Brazilian forward Liedson bruised his right thigh in Sporting's league game at the weekend but is expected to play.
Keeper Vladimir Stojkovic has recovered from a hip injury but 19-year-old Rui Patricio is likely to retain his place.
News conference: Man Utd boss Sir Alex Ferguson
Man Utd (from): Van der Sar, Kuszczak, Brown, Simpson, Ferdinand, Vidic, Evans, Evra, O'Shea, Ronaldo, Carrick, Anderson, Hargreaves, Fletcher, Nani, Giggs, Saha, Tevez.
Man Utd boss Sir Alex Ferguson:
"Sporting need to get a result, so we have to make sure that we don't play too many younger players on Tuesday.
"But the incentives are huge for us. If we win, we have won the group and therefore can look forward to being seeded when the draw is made for the knockout stages and that's important.
"We've also got an important game against Liverpool straight after the Roma game. Beating Sporting would allow us to rest players against Roma."
