Ancelotti's best decision was to add Bellingham to the squad. He is a great midfielder now. And he can become a worthy replacement for Modrich. We probably won't see Modrich at Madrid next season. Because he is now 38 years old. Bellingham's consistent good performances have led Madrid to continue in La Liga and the Champions League. Madrid will face a big problem if Bellingham is out of the squad due to injury.
Modrić is getting old and that's a fact about the 38-year-old palyer even until this time he had a good performance to play at this age for a great team like Real Madrid in the important match they had so far. I think Ancelotti made a good decision, but even this good decision had some consequences, and because of his decision of Ancelotti Modrić is about to leave Real Madrid.
