I'd be very surprised if United being better in the transfer market than Chelsea is the general opinion. We're the club that paid 4m over Fellaini's release clause because we missed the deadline. You'll fight a losing battle so don't even try.
ps- I do get the point though, and like i said earlier, not every deal will be simple and straight forward. But it shouldnt be a controversial opinion to say that you were better run under Roman/Marina, particularly in comparison to Boehly/Clearlake.
Was there even a 'battle' on who is/was the more incompetent at finalizing transfer between our clubs?
People just commented on your claim that under the previous regime we always used to do deals 'quietly and efficiently' which simply wasn't true. Still nobody said whether it was better or worse than United's dealings, just that it wasn't always great and maybe you simply weren't paying enough attention.
Generally speaking Marina was quite good at selling players and often less good at buying them. She was always seen as a very strict negotiator so when selling players she held to her own valuations, which quite often resulted in us getting some very good deals but also meant we sometimes had a very tough time getting rid of players when the buying clubs simply refused to meet the asking price and thus leading to the infamous 'loan army' of unwanted senior players who just went from one loan to another when a buyer couldn't be found at a 'good enough' value for Marina's liking.
Marina was also similarly strict when buying players to avoid overpaying which wasn't always appreciated within the opposing clubs and resulted in multiple deals breaking down over the years and having to go for worse alternatives instead, often at inflated prices too. The last bit was especially true around 2017-2018 when our primary targets were the likes of Lukaku, Alex Sandro, Van Dijk, Mahrez and Alisson but after pursuing all those players for a long time and failing we ended up with Morata, Emerson, Kepa etc. instead, not to mention at the same time throwing unnecessary money on dross like Drinkwater, Barkley and Zappacosta as well. Even if some of those completed deals were done 'quietly and efficiently' it was most of all a result of previous failings and a certain level of panic setting in.
I definitely agree that things were maybe run better under our previous regime and compared to some other clubs I could even say things went reasonably well overall, but it's easy to forget they had more than their fair share of failures too and this hyperbole around the new owners just screams of recency bias.
