yep, we probably dont need to worry too much even though Ancelotti failed to bring in a pure striker like Mbappe but the players that Real Madrid have still look very good with some of the players you mentioned, especially Vinicius and Bellingham who currently seem to be key players for Madrid to continue to get the winning score to win the title in UCL and on the one hand we dont know for sure whether Madrid really failed to bring in a striker player or whether it would be a surprise to be able to bring in a truly quality player.

mbappe or Haaland are both very suitable to be Real Madrid strikers, its just that these two players seem really difficult to get because the team that has these two players also has the goal of trying to try their hand at the UCL this season so it little difficult to recruit these high quality players.
but who knows if it will be surprise because money can change a football player mind and I am more comfortable waiting for whatever player will be brought to Real Madrid, of course the player has very good quality talent but I support you if Haaland will be better suitable compared to Mbappe.
