Ronaldo was one of, if not our best player in the last leg. He has been our best player in numerous big games, but people now judge him on goals scored, and that's not a fair assessment as he's not a striker. Better teams have better defences, so Ronaldo is used to unlock defences for someone else to score. Still, he didn't do too badly against Roma (several times).Man United should go through, and if they play anywhere near their best then they are all but through. Ronaldo doesnt perform enough in the big games for my liking, so about time he does. The key will be whoever keeps the other teams best two quiet will win (Rooney and Ronaldo or Benzema and Ben Arfa).
Also, I wouldn't say Benzema and Ben Arfa are Lyons best two players, probably Benzema, but I'd say Kallstrom and Juninho are both better players (though less exciting) than Ben Arfa at the current moment in time (though Juninho is no spring chicken now).
