Given that everyone is Talking about a striker, that Madrid needs one urgently, well, they are already seeing promising young players and it is not bad, here is a good example of what they may be looking for, however I would stay as they are , with Rodry , with Viniscius and Bellingham , for me they are the best , there is no other option.
With Vini Jnr, Bellingham and Rodrygo currently in the team their team looks really strong and good but I think it's not yet very balanced cause they need a quality striker that got a very good finishing and could be able to score week in and out, Joselu is a temporary player for the team and is not that type of striker that could do that and I don't even think Realmadrid would sign him permanently, even if they do he's not going be the top finisher for the team.
Mbappé has a connection with Realmadrid and could move their next summer,he's still on Madrid radar even though they're still or Alternatives for Benzema's replacement, but I think he's the preferred option for that role, his partnership with Vinicius Junior and Rodrygo would produce magic for the team coupled with Jude Bellingham would make it more Amazing, Realmadrid should seize their opportunity to get him when his contract expires by next summer.
Well I agree with you about this balance, it is true that the presence of the 3 players for now can cover the shortcomings that Real Madrid still has, but Real Madrid needs more than that, not just closing the shortcomings but they must really have a good balance. I know that it's impossible for a club to be perfect, there must be something that makes them have something that can be exploited by their opponents, but with them better it can at least create a kind of fortress where they can make it difficult for opponents to find their weak points.
