What is wrong with a 34 year old CB being a starter??
Liverpool just extended the contract of a 34 year old CB for another 2 years(same Van Dijk many of you wanted here as a free agent to replace Araujo). Sergio Ramos, Thiago Silva, Franco Baresi, Paulo Maldini, Cannavaro,Nesta,Puyol, etc , had some of their bests years between years 31-35
Barca will have about 5 CBs next season if the "30 year old" is added and even after selling Araujo and keeping Garcia. That should be enough to cover the CD positions and not need to waste the entire proceeds of 65m on another "budding" CD that will sit on the bench because you need to plan for "next 5 to 6 years" when you are almost insolvent. Its so pedestrian, bro!!!!!
Martinez was injured for a few times this season and Curbasi was also rested too, team was not "cooked". If team was not "cooked" then, it will not be "cooked" with an addition of Tah and the exit of Araujo....simple!! All of that dont justify spending 65m on a defender that will most likely sit on the bench for next few years until he is ready. Reason well, brother!
Imagine??

Do you have to sell a starter in a position that you are stacked while other areas need urgent reinforcements?? Besides, you admitted in your previous post that Araujo is not a starter nor very important for now so why speaking from both sides.
And even if he is sold for that money and a Tah is brought in for free, do you not think it is
vision myopic to pump that same 65m on another defender who may not be starting or any other player who will not be starting????
I don't know what "Football schools" teach this type of squad planning/management when you have insolvency and illiquidity staring you in the face. Perhaps the Community football clinics organized for 6-10 year old kids in the suburbs.
And certainly, I cant see any vision in any of your points above but inefficiencies in decisioning. Otherwise, nothing else will make someone who could not afford to pay his current bills but decided to sell his average age car for the reason of not being "technical" enough and used the sales proceeds to buy another car 'for the future" that will only be kept in the garage and useful in 5-6 years.
