The scoreline doesn't tell you anything. It only says United won.
I was thoroughly entertained and encouragingly heartened by the sight of United giving it their all in the second half after being second best in the first. Perhaps a good old-fashioned rollicking from SAF (a-la Tiger FC) did the trick. On came Giggs and the rest was history.
Ronaldo's first-half absence highlighted his importance to United; the second demonstrated Giggs'. Suddenly United were more incisive, more urgent, and the rewards duly came from the unlikely source of Vidic and more staple fare from Saha.
Solskjaer wrapped up proceedings and this would've done their confidence a world of good.
