Madrid's laxity this season was based on the depredation of injury on the players and they don't have any good replacement of similar quality. Signing TAA will improve and strengthen the defense, not only that, he is good at scoring goals. As for Rodrigo, let him do what pleases him, because I believe that his impact would be felt in Madrid in the future.
Real Madrid's defense is weak because Real Madrid's important player in the defender position is injured and since Dani Carvajal is absent there is no one who can replace his position so it is hoped that the arrival of TAA will make Real Madrid no longer confused in arranging the formation in the back line because TAA is a player who is quite good at being in that position. Regarding Rodrygo, it is reported that Liverpool is interested in recruiting this player, I think as an effort to replace the loss of TAA, but if Rodrygo is not interested in leaving I think he will continue to be at Real Madrid because it will certainly be very difficult for him to leave Madrid.
