England are at the top of their World Cup qualifying group with three wins from three games.
He said: “The lads are confident.
“You can imagine after the Croatia game last month that everyone was buzzing.
“We want to keep it going and we got another result at the weekend against Kazakhstan.
“We will be watching the videos on Belarus, so everyone in their minds will know exactly what they are good at and what they are not good at.
“No game at this level is easy. On Saturday we had to be patient and once the first goal had gone in, we went on from there.
“We won’t under-estimate them but if we work hard and pass the ball like we can do we should get the three points.
“Everything is looking good. The way we are playing, the whole set-up, the whole preparation before games is fantastic and we just want to keep it going.
“Everyone is confident now. We don’t want to get complacent now and we just want to keep winning games.
“We’ve got a massive goal difference now, but it doesn’t matter how many goals we score. As long as you get the three points, that is the crucial thing.”
