I think the stick he's getting here is a bit unfair tbh. If it does get confirmed tomorrow that it's officially Real, we've already had these stories to Bayern, then it would be very tough for anybody to turn that opportunity down. Correct me if I'm wrong but I don't think there has ever been so many English speakers at Real before either to help him fit in.
A) Status - Real Madrid, Cristiano Ronaldo, Carlo Ancelotti, La Decima - it's almost endless. The draw would turn all of our heads.
B) Training - To be alongside Ronaldo is the perfect education lesson to show him what it really takes to maximise that talent to reach the top. Then there's the speed and determination of Bale, the craft and hard work of Isco, the natural talent of James, the vision, technique and awareness of Kroos and Modric.
C) Style - Real have been using a less direct approach this season with a huge focus on ball control and working opportunities while allowing for solo dribbles and moments. It could be easily argued that those ideals suit Ødegaard's play more than anybody but Bayern. The technique and control in Spanish football coupled with the least physical nature from the big 3 leagues is also a great fit.
D) Pressure - the ultimate club for pressure. Draws are the new defeats and defeats are a crisis as Sid Lowe says. The lad has handled the watching eye thus far, life at Real will push that further than anywhere else immediately.
E) Carlo Ancelotti - A superb coach who is proficient with many systems and styles and an excellent man manager. Despite a track record of maximising already established players potential, there is no reason to suggest Ødegaard cannot thrive in a system eventually under Ancelotti. Paul Clement and Zinedine Zidane are also excellent trainers to spend time working with.
