All the footprints you've ever left and fear expecting ahead (Porto part 2)

I'm not going to do the usual preview today (and not only because I'm on a bit of a tight schedule today...), all the major players are fit and whoever plays we need big performances from, so speculating on a line up seems superflous. Yes, we need Ronaldo to step up, but we need everyone to step up along with him. And I'm pretty confident that that is precisely what's going to happen.
All the statistics about Porto and English teams - well, does it really matter.? It shouldn't affect what happens on the pitch. We are the better team, and if we play well, we'll go through. Even though we didn't perform at our best first leg we were still minutes from winning the game, so we must know we're good enough. Hopefully Porto will be in two minds about sitting back and defending their away goal advantage or going for the jugular and we'll be able to take full advantage of that. The Telegraph:

The need to outscore Porto could suit United. Porto face a tactical dilemma – do they sit on an away-goal lead or kill the game off?

I would normally at this point nick a few facts from the BBC, however, their facts seem a touch negative. So I won't. Not going to ruin my positive thoughts... "You can prove anything with facts..."
Prediction. A 1-0 victory to us. And a night full of tension...
