After being left by Benzema, Real Madrid have not found a suitable replacement, now there are rumors with several players like Kane or Mbappe, I'm sure one of them will be brought in, Real Madrid's failure in the UCL and La Liga last season certainly made them will improve more to be able to appear stronger in the next season.
As for the replacement for Benzema there is no news on which player Real Madrid will buy, but some news circulating in the media is that Kylian Mbappe is a priority that Real Madrid is trying to approach. Learn from last season and Real Madrid must really maximize the quality of the players they want to bring in because if you rely on existing players it will be difficult to compete in any competition next season.
Kylian Mbappe is one of the players Perez most wants to replace Benzema, but so far no agreement has occurred between Real Madrid and PSG regarding the transfer of the player. Real Madrid need to move quickly to finalize the transfer of Kylian Mbappe as Liverpool are also interested in him.
Last season was not in favor of Real Madrid, only the CDR trophy that they managed to bring home from the several competitions they played in. Real Madrid needs to immediately spend money to bring in players while there are still several quality players available in the transfer market, Harry Kane can also be used as an alternative if they fail to land Mbappe at the Santiago Bernabeu.
Real Madrid would love to do it quickly, but there isn't really anything they can do about it except for making their offer. Kylian Mbappe has time and PSG also has time as they don't even have a new coach yet. The transfer market is also open for quite a while and since there is no pressure for Mbappe to rush it, he is probably waiting to see what other clubs might also be willing to offer him. This deal is far from done yet and rumors keep this whole story alive on a daily basis. Liverpool was mentioned and I would not be surprised if a couple of other names also will be mentioned.
