Real Madrid coach Carlo Ancelotti has welcomed Endrick's visit.
The Palmeiras striker will join Real later in 2024 and is in Madrid this weekend.
Ancelotti said: "My advice for the young lads is to enjoy the moment. He's progressing really well, we're thrilled that he'll be our player from July. I hope he enjoys this spell. He came over to see us and to watch the game and we chatted with him for a while, but we have to wait until July now.
He's learning Spanish. He's delighted with what he's been able to achieve. He's done a brilliant job for his team and they've won a couple of trophies. He's enjoying himself but he's focused on what he has to do with the national side at the Olympics."
On his own contract, Ancelotti added: Being Real Madrid coach is the most important thing. I hope the players will give me a Christmas present by winning the last couple of games so we can have a relaxed festive period. If the club is happy then I am too. There is no rush to renew my deal, it's not a problem. We're here until 30 June 2024."
