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.
Real Madrid's manager Carlo Ancelotti have confirmed not sign any players yet in this transfer window and Kylian Mbappe is not in his transfer players name list, I think he has enough with current striker right now Vinicius Junior, Jude Bellingham, Rodrygo and Joselu.
Not really bad with Real Madrid attacking line performance in this season because they have good performance between Champion League and La Liga.
But not close with opportunity for next season to sign Mbappe because he will be free agent but Real Madrid want to focus on Champion League and lead until final round than get difficult way for signing Mbappe.
