Roma's D looked shaky and unstable at best. Their style almost made them fall out of organization. They really need some leadership at the back, and Panucci isn't it.
They played well from the start in terms of keeping the pressure on, but they were also up one man for most of the game. Their biggest mistake was taking the foot off the gas not long after halftime. Say what you will about Ronaldo's play, but he made dangerous runs through Roma's rather shaky defensive midfield. He was probably ManU's most effective player on the night. Scholes was utter crap and arguably almost helped ManU by staying off the pitch!
I think Taddei is an ass, but he had a good match. But best of all the bunch, IMO, and even better than Chivu, was probably Mancini (not a big surprise there). He had a direct hand in setting up both goals.
ManU notched an away goal and only a one goal down with 10 men. I hardly see that has putting them on the backfoot. If anything, I would award them with the moral victory of the more favorable result. Roma really should have come away with a 3-1 under the circumstances. My bet is they will rue that in a week, though they're well over their heads in the CL quarterfinals without a huge dose of luck in their favor.
