The 29-year-old has an excellent record at international level after scoring 20 goals in 37 matches, but he has still been behind Emile Heskey in Fabio Capello's plans.
Crouch said in the Daily Mail when asked if he was frustrated not to be a first-team regular for England: "Yes, sometimes. All I can do is take the opportunities when I get them.
"Hopefully, I did well enough scoring twice in the last game against Egypt to play a big part in the next one, against Mexico, and in the World Cup."
He added: "In the back of your mind, it helps to know the manager seems to prefer to play with a big striker, although he has got other options.
"The truth is there are a lot of forwards who want to play alongside Wayne Rooney and I am one of those."
