Guys guys.. You are looking at this from a wrong prospective.
When Nedved got sent off in the first half I was worried that we were going to lose the game. Then the 2nd half started. To tell you the truth, it felt like we were playing either 5-4-1 or 4-5-1. Until the last 7-8 min of the match you could hardly tell that we were missing a player for such a long period. Roma might have been playing with not their optimum squad but just for you to know they are very strong. A team that can win 11 times in a raw is a team that is really fearable. Ok they were missing Totti and De Rosi. Still we were playing more than 45 min with 10 players. Let alone we have another match to think about in 3 days.
Our performance in the 2nd half was VERY SOLID. We were not creative, but we were solid. We did not give Roma spaces (a team who is not exhaust as your team playing with an extra player for 45+ min you'd expect them to make spaces). Even more in some parts of the 2nd half I felt that we were going to score the 2nd goal.
Bring on Balzaretti instead of Mutu was wize. Might not be fancy, but wize. This is a kind of mentality that looks into all sorts of conditions and keeps in mind the opponents capabilities and respects them.
Am I worried about the Arsenal game? yes I am, but the day I stop worried it is either that the trophies is 100% secured OR I am dead.
