Jese played with Mbappe on-loan from Real Madrid.
Jese said, "Mbappé told me that he was going to play for Real Madrid one day. I didn't know if it was in a year, in two years, in three years.
"It is a bit complicated but in the end in the world of football something new comes out every day, something that surprises you. Although also knowing Florentino (Perez, Real Madrid president) to know everything he has spoken with him.
"He will end up playing here. I'm sure. I don't know if now or next season."
