The problem is now with Carvajal, his gametime management and subsequent future development. A player with a pricetag of nearly 40m that comes in to a team like this will most likely get to start many games just because of the price alone, and thus get the lions share of gametime that would otherwise go to Carvajal. In the beginning Danilo will need to play enough to get integrated into the team and Ancelottis system to the point where they can start fairly evaluating his performances, and then from there start implementing a real meritocracy between him and Carvajal.
If Danilo turns out to be as good as he is hyped to be, this could spell "the bench" for Carvajal. Will he be satisfied going from being a starter with RM, and a player working his way into the starting 11 of Spains NT, to becoming a benchwarmer for Danilo? Obviously not. Danilo is probably the one of the two who will have the least issue with accepting the bench in the beginning, but his price demands gametime, and if he also turns out to be better than Carvajal when he plays, then even more so. On the other hand if Carvajal wins the battle of gametime, then RM have spent 40m on a player sitting on the bench - a player with great talent and potential who needs gametime to develop further.
Having two young and talented players both with the ambition of being starters for their club and NT playing in the same position is tricky and very difficult to manage. This just shows how hard it is to find players willing to sit on the bench, but who are also good enough to keep the required level when called upon. RM could really have bought themselves a
real headache (pun sort of intended
), as in the end I don't think either of them will be happy with being a benchplayer - and one of them has to.
