Juventus got Jonathan David for a striker, hence why they didn't get Osimhen. Sure you may think Osimhen is better, but the difference is that you need to pay 20 million a year on Osimhen plus 75 million transfer fee, whereas David was free, and cheaper salary. They already spent 100+ million, and with their sale, they are at minus -50 million right now.
I guess the best case for the time being is the recovery and if they can be safely handle the finances, they will do fine. I get that it may not be easy, but they can definitely control this and should be happy about it. I get that it may not be a big deal to finish 4th or whatever, but it is going to be horrible if they pay more, spend more, try to be first, and then fail.
Most of the Italian top clubs suffering badly in finances which is now also having huge impact on their performance Jonathan David is free, but surely he is not going to perform like Victor Osimhen who is match winner at any club due to his quality and consistency.
After pandemic things are not favourable for many big Italian clubs which are surely having impact on them, and they consistently fail to give their best Jonathan David is also young with have good performance at Lille which can give him good boost, and he could be good for Juventus in coming season but still they needed to be had few top names into their squad which can bring good performance, and they are able to win big in Europe.
