He said, "He just gave me a message saying I'm playing well, I'm close and I deserve to be there but he's going to stick with the same team.
"That's football, I'm not too fussed about that.
"I can take the time off, go see my grandparents, and it's not the end of the world as there's another camp next month.
"I'm just focusing on Crystal Palace and playing well and hopefully if I play well I'll get the call."
