It is very unlikely that Real Madrid will recruit Haaland after they succeeded in bringing in Mbappe, after all these two players cannot be played at the same time because they play in the same position. It's enough for Real Madrid to bring in a quality striker, what is needed now is all in Mbappe.
Real Madrid front line is very complete, they also have quality reserve players who can play in the same area. Real Madrid may bring in one or two more players before the transfer window closes, but it is certain that the player they will bring in will not be a striker because it is no longer their priority.
Real Madrid already has Kylian Mbappe so why should they recruit Erling Haaland? These two players have almost equal performance on the front line. Apart from that, Real Madrid will not spend a lot of money to recruit players like Erling Haaland because Erling Haaland has a fairly high price so why would they dig deep into their pockets when they already have star players in them? In fact, it wouldn't be good for Real Madrid to have many star players, it would create competition between players, besides that they would fight each other to play as the main player even though as strikers they couldn't play simultaneously.
Yes, Real Madrid already has a very complete squad and has good performance, so Real Madrid doesn't need to recruit Erling Haaland. Many star players will not be good for the club itself, just like when PSG when they have star players like Neymar, Mbappe and Messi, the club doesn't can achieve success because star players prioritize their egos to perform well according to themselves without requiring cooperation between players just because the most important thing is for them to win individual titles.
