It is written that Nico Williams wants to stay in Spain and if Bracelona manage to buy him, then it is logical that Dani Olmo would be a good acquisition to pair with Williams, because they played well at the European Championship together.
It seems to me that it is better to buy a player like Dani Olmo than to take 18 year old rookies for 50 million euros, like Real Madrid and Manchester United did.
It is written that Barcelona can get the money to buy players from the sale of Gundogan to the Saudi league. Gundogan himself apparently would like to stay, but without his sale there may not be enough money to buy Williams and Olmo.
The impressive performance of Nico Williams and Olmo when strengthening Spain in the Euro caught Barcelona's attention to recruit these two players and even Barcelona has confirmed that they will recruit both players but finances are still a problem for the team.
Regardless of whether it is better or not, Barcelona must build this team with all its limitations, it will be quite difficult.
Not only Gundogan but Barcelona plans to sell some of its players to get fresh money so they can make several other purchases to improve the team's performance.
Barcelona has experienced this for the past few seasons, and I am quite confident that they will be able to realize some of their desires regardless of the method they will use.
