The Liverpool striker has grabbed four goals in the qualifying campaign and remains confident that the Three Lions can make it to the European Championship next summer.
Speaking exclusively to TheFA.com, Crouch said: "I think we've believed all the way through, we had a bit of a sticky start to qualifying but we've certainly improved since then.
"We're playing some good football now and it's a shame that we're relying on other teams now, but we're certainly confident that we'll get the right result and hopefully the other teams will do us a favour."
Crouch admits that everyone in the squad is determined to put that result behind in these two games.
"It's a big factor. Before that game everyone was happy with the way we were playing, we had a few 3-0 wins and we were playing some great football.
"For a large part of the game in Russia we played very well, but it was just a mad ten minutes and I would say that that was a hiccup and hopefully we can put that behind us with these two matches."
