Alvarez still needs game time so that he can improve and that will develop even more when he can play regularly in the team.
Being a substitute will not make his performance better, like when he played at Manchester City.
Therefore Alvarez needs to get more game time so that his skills can improve.
Mbappe has been a great player for both club and country, so comparing the two is not fair and Mbappe is certainly superior in many ways.
Julián Álvarez will be able to contribute greatly to Atletico Madrid and Mbappe to Real Madrid.
I think right now especially Mbappe's transfer is very exaggerated so that there are high expectations for his performance with Real Madrid so that many people forget that Mbappe also needs time to adapt to his new team, so I think we just have to wait for the time for Mbappe to develop.
Bellingham's back as well. His link with Mbappé could be exceptional. Real Madrid's offensive might reach entirely fresh dimensions. Thus, indeed, Mbappé is the focus of all eyes. Still, the true difference will come from his settling in at true Madrid. Should he continue to grow on this early success, we might find ourselves in a season where he at last finds those club trophies he has been after. And that, my friends, would be huge for Real Madrid.
