From a sporting perspective, I think we are on a mini rejuvenation revolution, where 2-3 young studs are added every year, which imo is a good way to go about it.
From a financial one, we have accumulated a lot of dead weight and have a coach that's to say the least is not an asset at this point. Both of these issues can largely be blamed on our effort to rebrand who we are. Going for Ronaldo meant we had to get creative in other areas and also go for success now as opposed to building for the future. Also getting sarri is imo 100% financial decision, we want a more marketable football to generate more revenue.
With these constraints in mind, i believe we need a solid LB, winger, and striker, these are the absolute needs imo getting another CM would be luxury at this point since those needs i mentioned are more pressing imo.
