We know that Arda Güler complains that he doesn't get enough minutes. Especially in the Turkish press, there is a lot of news about this issue. I think he will leave Real Madrid at the end of the season. It would be best for his career if he leaves on loan and goes to the Premier League. Arda Güler is currently a side character at Real Madrid as a substitute player. At Bournemouth he can find enough minutes and become the main character. He has the potential to do that. He is only 20 years old. But he doesn't like being a substitute. I think he is a boy with a leader spirit. He can improve himself at Bournemouth. And he can move up a level.
I am not sure that Real Madrid will send Endrick or Arda Güler to England to facilitate the deal for Dean Huijsen. These young players are seen as the future if the club and Carlo Ancelotti usually use them as substitutes.
I checked on a few news outlets, and it seems these players will not be sent to Bournemouth. Rather Fran García will be sacrificed for the deal to go through. Since Dean is worth 50 million euros, Garcia will reduce the fee to 35 million euros since he is worth 15 million euros. Endrick and Gular are a priceless assets of Madrid, and they will always remain in Bernebue Santiago Bernabéu.
