right @barisbilgili, i agree with you, Modric's quality is indisputable but age advances for everyone, even for him, and it could affect his performances and if it doesn't affect them it could cause problems with physical fitness and injuries
This is the risk of having older players, we just have to take note of it
Yes, it's true, age advances for everyone, but there are players who have given their best when they were older rather than when they were young. i am not saying this to necessarily say the opposite of what you say, it's just to say that you don't know if a player can give his best even at a certain age, it depends on many factors.
