Sir Alex Fergueson and Manchester United know there is only one result for them which can help them put themselves on the way to Rome, and that is victory at the Estadio do Drago.

Porto are clearly the side who should be favorites but not as much as the bookies seem, and I expect as we approach game time, much of the money will be on the draw, because thats all that Porto need.

Porto will take great heart from getting 2 goals at Old Trafford, once and unpenetrable place for teams to come, and United have now had a terrible record leaking 10 goals in 4 games, which is why United thought it good to rest Edwin van der Sar for the weekend clash against Sunderland, to get him fully focussed on getting the win on Wednesday night.

Other key things for Manchester United is that barring injuries to Rafael, Hargreaves, Rio Ferdinand, most of the squad is completely fit and Sir Alex will actually have a selection headache especailly in the middle of the park. Expect experienced talisman Ryan Giggs to definitely start this game, as his experience will be crucial for the team in such a pressure situation.

Cristiano Ronaldo will be the one who will have to step up and be counted in his home country, as he had a minor outing this weekend, and should be the freshest of the lot to secure result.

Manchester United are going for an unprecedented 5 trophies, and they should least expect Porto of all teams to stop them from achieving this result.
