That's the thing, though, isn't it? As manager, your job isn't to simply think, your job is to assess and plan ahead.
The team structure is what creates the chances, and the forwards are paid the big bucks to convert them. The underlying statistics at the end of 20/21 suggested that we were massively over-performing in the final third. We didn't lack finishers, we lacked nuances in our game plan. So, if the idea behind signing Ronaldo was to add a "cheat code" that would allow Solskjaer to bypass the necessary process managers are paid to oversee and propel us into a title charge, it was a bad idea. It also (kind of) justifies all the people who were claiming at the time that Solsjkaer - despite his good intentions - was never the right man for the job.
There's a misconception about RvP's transfer. Sir Alex didn't sign him to "solve" any structural issues, but to spearhead an already potent team. He wanted him to replace a declining Rooney as the focal point of our attack. But the team already knew how to get those goals. In fact, the season before (11/12), we scored more goals (89) than with RvP (86).
