It's true what you said that the strategy of the coach and players is closely related to the club's success in pursuing targets at the end of the season and Luca Modric was able to adapt to the strategy implemented by the Real Madrid coach since joining in August 2012 until now being coached by Carlo Ancelotti. But with his age now will definitely affect his performance in the future.
Luca Modric's age, who is 36 at the moment, is the main thing that has influenced his performance at Real Madrid and I think it's time to replace him with a younger player for next season with the potential and performance that is not much different from Luca Modric. Because historically Real Madrid is a club that is very well known for its performance and strength in winning every trophy in the League.
