The Frenchman was outstanding in victory at Fenerbahce and said: "At United, I didn't have to shout that much to guide my partners. It is a responsibility, but when I signed for Arsenal I accepted it straight away.
"It was not easy to come here with a good atmosphere against us and I think we coped not too bad with the experienced players we played against.
"It was a good game to improve and learn from. Hopefully we can get some consistency."
Silvestre added on Arsenal TV Online: "We are looking to guarantee that we finish top of this group as early as possible so that we can get ready for the next step.
"Our aim is to play the kind of football that can take us to the final."
