Crouch started just nine Premier League game last term and has hinted his future could be away from Anfield unless he is given a more prominent role.
"I have spoken to Rafa. I have to play more games if I want to stay in the England set-up," he told the Daily Star Sunday.
"I didn't play enough last season, that's for sure.
"I need to play more at club level to be able to play at international level. You have got to be noticed.
"I need to play more games. I didn't get enough and it's something I have to look out for, for next season."
