Rodriguez and Adam Lallana will join Saints teammate Ricki Lambert in the England setup today.
"I am not sure what to expect," Rodriguez told the Daily Echo. "I spoke to Rickie and he just said it was a great experience and that the lads are great.
"He came back from it with a lot of confidence and it is just an unbelievable experience. I can't wait."
The 24-year-old added: "You look at the players (in the squad). It is an unbelievable experience playing against them, so actually playing with them will be excellent for me."
