Is a one goal lead enough to see us through?

Following one of the best team performances of the year against Arsenal in the first leg of the Champions League semi final, United fans must feel that the scoreline does not justify the dominance that United showed throughout the game. Chance after chance was wasted or saved by the impressive Almunia. John O'Sheas strike is all United have to carry to Old Trafford plus the fact that Arsenal have no away goal. Will this slender lead be enough to see United through to the final for a second successive year? What do you think the score will be in the second leg?
