Real Madrid may not make the same mistakes as last season. Last season, Real Madrid's injury woes left them among the weakest teams in La Liga. Although they finished the season in second place, the biggest concern was their lack of attention from Barcelona. They failed to win against Barcelona last season.
So they may be looking to sign some extra players to keep both the field and the bench in Real Madrid's favor. Last season, their main problem was defense, which they identified and fixed. Now they may be looking for replacements so that the team doesn't suffer any negative effects even if the team starts to suffer from injuries.
Of a truth they were affected last season with a large numbers of injured players. Hopefully most of the players are back if not all of them. Also, they also had managerial issues last season which has been fixed, because I saw a different Real Madrid during the Club world Cup tournaments. But subsequently they have to do better, if they want to win the Laliga next season. Because the current Barcelona team is still far better than the entire Real Madrid team. Only that, Arnold presence in the their team made a huge impact.
