While age had some effect on Modrich's performance, I didn't notice much of an age effect on Toni Kroos's performance. Toni Kroos has performed well in Real Madrid's jersey in the last season and he has also shown good flashes for his team, so if Real Madrid were to extend the contract with this midfielder for another season, this player might not have disappointed Real Madrid at all. As Real Madrid have decided against them, there is nothing they can do next season without these two experienced players. However, since Real Madrid is a professional team, we expect their performance to be stable. The two experienced players may have left their club but there are still plenty of young players in Real Madrid who will certainly do well in their midfield and will not miss the absence of these two stars too much.
Well I agree about this. Toni Kroos still looks reliable in his position at Real Madrid. Because he is not as old as Modric. he was only 34 years old. Meanwhile, Modric is 38 years old. And yes, we also see that Toni Kroos' performance is quite good if he can play again for Real Madrid for at least one more season. But Toni Kroos had intended to retire and yes, he realized his wish to retire this season. Last season Toni Kroos was also going to retire but he changed his mind and then decided to continue for one season and well in the end he can now leave Real Madrid in peace after successfully winning the LaLiga and UCL titles together. Meanwhile, Modrid is actually ready to extend his contract, but I haven't heard any news about that and it looks like he will be released if there is no contract extension again. And Madrid actually already has a player who can replace Modric since last season. So we often see Modric only playing in the second half or he often sits on the bench. Real Madrid is now ready with a younger generation.
