To be fair replacements for Kompany, Aguero, D Silva, Sane, Yaya, Zaba are not exactly knocking on our door and priced within the boundaries of FFP, especially at anything like a reasonable price. What would any of them have cost when at their peak. Should we buy the currently most expensive players in each of those positions, it won't guarantee anything, they may get injured like Mendy or Stones or Laporte, or turn out to be 1 or 2 season wonders being replaced as media darlings by another Haaland with multi million buy out clauses and long term contracts hastily attached after a few CL appearances. Fernandinho's birth cert. and the loss of defensive experience is a clue to his move, he cannot play 60 games in CM and every time he has to be rested the rhythm is upset again so maybe they decided he could do a job at CB and help Rodri on the pitch. A natural finisher like Aguero, who is brilliant but has always missed a lot of relatively easy chances would cost up to 200 million and even that wouldn't buy a young proven striker with his goals per game ratio. Also any proven player of their quality will want almost guaranteed weekly pitch time and competing at our level that is not feasible unless like now we have an injury crisis. Bravo was in the Copa America team of the tournament & keeper of the tournament in 2015 & 2016 with Chile and has a list of honours with Barcelona so he was not some unknown hopeful when signed and many keepers' of his experience would not be prepared to sit on the bench week after week so he was I think a very reasonable signing, especially with his knack of saving Liverpool penalties. What you say is valid but I think is the empty half of the glass when our current status puts it in perspective.
