"I think we lacked a little bit of a cutting edge in the final third, but that isn't a worry because there are some big players missing for England at the moment," Gerrard told reporters.
"If we can get Rooney and Sturridge fit they will be two big players for us, and they are the type of players you will need to break down the two teams we are coming up against.
"Our record is quite good at Wembley. We proved that by beating Brazil there so if we defend as we did against Ukraine and have a little bit more of that cutting edge in the final third, we will get there. I am really confident we can get the job done."
England host Montenegro and Poland at Wembley next month.
