I don't think, I quite confidently state that ozil is more naturally talented than di maria. His touch, vision and skills are better than di marias, among other things and while he was a big game bottler at real, di maria was worse until the second half of last season in his midfield role . He was clearly the better player in his first three seasons. However like I stated earlier, di maria has a better attitude and works harder and is more flexible and last year in a midfield role played at a level higher than ozil ever has. If ozil can overcome the weak mentality he has (especially in big games) he will realise his potential and become the player he is capable of being (world class and among the best).
