Many people get butt hurt after Guler joined Real Madrid because there have been a lot rumor he would join Barcelona, I think it's because Barcelona has financial difficulty, that's make them don't want to spend a lot money to sign Guler. Guler is a young experienced player, he have played for Fenerbahce for 2 seasons and Euro qualification. If Guler is too young for 18 years old to join Real Madrid, what about Endrick where's he only 16 years old and Real Madrid had spent 70 Million Euros to sign him.
The club's financial situation makes it difficult for Barcelona to sign players who have a high market value and they prefer players who have a low bid value but have proven quality. Guler is also one of the long-term prospects for Real Madrid and they can invest in young players for potential for the next few seasons because Real Madrid has the stable finances to make long-term prospects, as did 16-year-old Endrick.
Barcelona need the right players in an unstable financial condition like now and they have to look for players who have a value that is not too high and vice versa with a salary. Even though Guler was rumored to have moved to Barcelona, in the end Real Madrid was much better prepared to accommodate the player.
