Now it depends on performance whether he can show what Madrid expects or not because if he doesn't then it will be very difficult for his future.
But on the other hand I still feel that in this case Madrid will try to give him hours to adapt to be better, the reason is simple, Kroos and Modric are getting older and indeed now is the right thing to give some young players a chance with their current condition.
I agree with this because only a good performance can save themselves from Madrid because when it is not then it is very difficult especially since Madrid can also still be said to be one of the clubs that is quite assertive especially with poor performance.
Many examples of those who fail to perform well are always reserves even for a long time and in recent seasons of course Mariano and Hazard are one example.
On the other hand, it is possible that this season there must be rejuvenation for the Madrid squad because as you say the age of Kroos and Modric is no longer young now and of course looking at the current conditions with Tchouameni, Jude and Valverde it can still be for midfield. as for the wing line there are already Vini and Rodrygo there is only a matter of seeing the attacker or targetman this time who will be the choice.
Now I still feel that Ancelotti will still provide the same opportunity for some young players to be better prepared.
On the other hand, the trio of Jude, Tchouameni and Valverde, as you said, maybe that could be another option, although in this case we cannot rule out Kroos and Modric, but regeneration must still exist and these players, including Jude, who has just arrived, can be the backbone new to the midfield of Madrid.
