England won 3-1 away to Belarus last night, after two goals by Rooney and one by Gerrart.
Rooney said: “It was a difficult game and they played really well in the first half.
“We had to work hard — and we did that.
“Steven’s goal was a great finish from 30 yards. Emile Heskey did brilliantly for my first and it was a good ball from Stevie for the second.
“We’re pleased with the goals but the three points were more important.”
He added: “We have got that belief to win now. They had a lot of bodies in midfield and it was difficult to get round them, so the manager told us to keep possession — and that helped us.
“But we are going into games believing we can win them, with a lot of confidence.
“Goals are going in for me at the moment, which is good. I work on my finishing every day. I always have done. Things are going great for me on the pitch.
“But I can always improve, there are weaknesses there.
“I’ve worked with the boss since he took charge on finishing a lot of the time and it’s starting to pay off. I’m always going to believe I am going to score when I go out there, I’m a confident person.
“We have worked really hard to be in the position we are in and now we’ve got to keep working hard. We are in a comfortable position now and we need to get as many points as possible over the remaining games.”
