Real Madrid is re-building their teams in order to perform well in the Champions League next season. Since Manchester City eliminated them, they are attempting to sign new players to replace those who have left. Madrid is attempting to bring Mbappe to the team in order to replace Benzema; if Madrid signs him, they will be stronger than before. We need to sign a new defender to replace Nacho Fernandez because his performance is very poor and he is getting older.
It may happen next year but not for this year. Perez has been clearly stated that if real madrid will not pay price offered by PSG. Madrid is still able waiting for mbappe to leave from PSG with free agent.
You can't hope it to happen now caused by the real madrid president has been confirming it. Football is dynamic but i do believe any words that have been coming from perez.
Madrid will not be wasting a lot of money for a player. There are lots of things that can be done with such money.
