I can say that Real Madrid, Barcelona and Atletico Madrid have been successful in this transfer market. Real Madrid became the most successful club because they managed to get one of the best strikers in the world today, Kylian Mbappe on a free transfer. Atletico Madrid managed to get Julian Alvarez from City. I also agree that Alvarez is a player that Simeone really needs to perfect his tactics this season. And finally, there is good news for Barcelona fans because they managed to get Dani Olmo. But there is news that Barcelona still cannot register Olmo because they still cannot meet the FFP rules.
But it can't be denied that for now the most successful is Madrid. We can see when comparing the costs incurred in the transfer this time Atletico had to spend at least approximately 140 million for Julian Alvarez, Sorloth and Robin Le Normand even though the price was quite a bit actually with the arrival of the players they did at this time. Barcelona had to spend 60 million on Pau Victor and Dani Olmo this time although that is also a price that seems normal for player fees. But if the comparison is with Madrid then obviously Madrid is much more profitable in the transfers they are doing at the moment they spend around 47 million but they get a player of Mbappe's caliber on a free transfer and of course Endrick who they brought in quite expensive although I don't really like his style which seems a little arrogant but I think he can be very reliable especially with his young age at this time.
