Arda Guler currently was targetting at least 8 clubs and most of them is from Laliga clubs such as Getafe, Real Sociedad, Sevilla, Las Palmas, dan RCD Mallorca
Even if Arda Güler goes on loan I wouldn't expect him to sign for teams like Getafe, Las Palmas and Mallorca. Even Sevilla look doubtful because of being far away from their good times.
There is no need for him to waste his talent at struggling teams. He should have decent players around him to show his skills easier. However it doesn't look like he is leaving on loan this summer either. Ancelotti is confident of that as Arda Güler also wants to stay. Of course there is going to be a really tough challenge for him at such team. Especially after Mbappe the competition level is increasing more in specific areas. I hope Ancelotti gives chances to Arda Güler anyway.

Because Greenwood will return to England at the end of his loan period and the Getafe club is now looking for options in the transfer market. Arda Guler is the main candidate to replace the English player. However, Real Madrid have clear plans for Guler and they intend to include him in the first-team squad for next season. This proves Carlo Ancelotti's confidence in his abilities. Therefore, even though Getafe is interested in borrowing Guler, Real Madrid management believes that keeping the young midfielder in their team will be more beneficial for his development and the needs of the team as a whole.
Arda Guler joined the Spanish giants last summer from Fenerbahce, he has had an outstanding season. Guler managed to make a significant impact after he made his league debut in January, scoring six goals in just 10 appearances, with four of them as starts. I agree with your opinion, even if Guler moves clubs, he should play at a big club, not like Getafe or a lower-class club. According to my observations, Real Madrid will not sell, let alone loan, their future players.
