Southampton striker Jay Rodriguez is unsure what to expect from this week's England chance.
Saints team-mates Rickie Lambert and Adam Lallana have also been included in Roy Hodgson's squad, with the trio travelling up to St George's Park on Tuesday.
"I am not sure what to expect," Rodriguez said. "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.
"You look at the players. It is an unbelievable experience playing against them, so actually playing with them will be excellent for me."
