If Osimhem is the striker that Real Madrid is targeting then in the previous transfer market Real Madrid will definitely make an offer to Napoli and I'm sure it will be difficult for Napoli to refuse that offer. But in fact, Real Madrid did not make Osimhen their main target and still favored Mbappe as one of their desired targets. Mbappe has much better advantages compared to Haaland because this typical player is much stronger and masters playing positions on the wing or as a central striker.
I was fuming some weeks back before the beginning of the season why Anceloti never bring in new striker to Real Madrid squad when the market transfer was closed because the only good signing I saw from the list was Bellingham but for tbe job of midfielder. I was not having it how he intend to manage that forward task with Vinicious and Rodrigo but subsequently, Bellingham fit there and he was okay for that place even when he wasn't bought for that role. With such result, I don't think they made move for Osimhen in the first place.
Haaland is only able to complete passes to score goals, but speaking of needs I believe Haaland and Mbappe are two figures that Real Madrid really needs. If both of them can be brought in in the next transfer market then I think the Real Madrid squad will be much better and will produce striker who are quite feared by any opponent.
What you think Real Madrid need but they already made the decision of not getting any new player right from beginning of the season, but now I think with the injury crisis in the club after Alana went on another injury, they have no choice but to look for more competent players because there 4 good men are out, Vinicious return next month is still under uncertainty.
