You're ignoring what I'm saying. We tried exactly that when we signed the likes of ADM, Sanchez, Pogba, Mkhitaryan, Schweinsteiger, Ibra, Depay. With the exception of Ibra and Schweinsteiger, all of them were either approaching or at their peak, and in Depay we had one of the most sought-after young players in Europe. Almost all of them flopped or flattered to deceive. All of those purchases have basically accounted for close to 280m in transfer fees alone; let alone their wages.
Quality alone is useless if the person doesn't want to be here or isn't committed and bought in to the project. We went down the route of bringing in those players, budget be damned; and where did it leave us? ADM was kept out of the side by Ashley fecking Young on merit by the end of his season, ffs!
