The Brazilian, who has been linked with a move to Everton in recent weeks, is keen on leaving Russia.
“Until now the only concrete offer I have received came from Everton in England,” he told Globoesporte.
“There wasn’t any contact (with Real Madrid) but it would be wonderful. Every player’s dream is to represent Real Madrid.
“Certainly I would do the possible and impossible to be released by the CSKA president.
“Because of the work I have been doing here I think I deserve to be called up (by Brazil). But the boss, Dunga, has other options and called great players up too.
“That is also a reason to join Real. If I were scoring so many goals for a mid-European giant, I am sure I would be called.”
