Modric's quality is very good.
No doubt, Modric, even though he is no longer young, is a player that Rea Madrid really needs at the moment. I can't help but hope that when he first came to Real Madrid, he had to struggle hard, from being called the worst signing in the league to becoming the best player in the world. His name was also not as big as other midfielders when he came to Real Madrid, but Modric proved it with hard work and a good attitude.
There are no players who can replace it regularly. So as long as he's still fit enough then I think it's not a hindrance. The management and coach certainly understand the condition of the players, so at this time Modric also started more matches from the reserves. Anceloti has understood that his age will not be effective to play for 90 minutes continuously. Belingham's arrival has helped Anceloti, and he already has a replacement. Although I think Belingham needs friends if it is true later Kroos and Modric
Yes, it's true, of course he's not as strong and not as effective as before when playing 90 minutes, but Ancelotti knows his presence on the pitch is really needed to raise the enthusiasm of the young players. In big matches like El Clasico and UCL he remains Ancelotti's choice.
