They also tend to get business done early or else they risk having potential sellers refusing to accept anything but a silly bid because they know we're desperate to buy. See Antony/Fellaini/Casemiro/Hojlund etc
United transfers since Fergie left have been far more in the category of doing business late and massively overpaying than business done early.
I'm fine with us signing Cunha and then bringing Rashford back into the squad as competition unless we receive a suitable offer, same for Anthony. This should be the club's official stance since while ultimately I think neither are good enough to get us winning premier leagues or champions leagues they're both assets who would improve our squad and we shouldn't be paying them to play elsewhere.
There's no doubt that Cunha is a good player.
However top honors aren't won by individuals. It's won by having a good balance in the team. SAF's last side was possibly the weakest throughout his reign and it won the EPL title. There are other sides who weren't spectacularly good but had the right balance to win some important trophies including Euro winner Greece and Italy, Ranieri's Leicester, Zaccheroni's and Pioli's AC Milan + a countless number of Juventus sides.
When I watch United I can see 4 major weaknesses
a- STK. Neither striker is good enough to be an EPL striker. Zirkzee is a no 10 while Hojlund's positioning and movement is simply not good enough. I think that we need at least 1 striker, possibly 2 (a top striker and a cover Delap style)
b- GK: Neither keeper is good enough for United as well. That's a problem because defenders are programmed to defend against what's in front of them not at their back. When they lose trust in the GK then mistakes will happen irrespective if the CB is Heaven/Yoro or Rio/Stam
c- CM. Our CM is simply too lightweight for the EPL. Ugarte does the job but he's no Roy Keane and he therefore needs help. Casemiro can't provide that on week in week out basis, Mainoo is not athletic enough, Mount is a no 10 and Eriksen's legs are gone. We need a B2B midfielder, possibly also a DM as cover for Ugarte.
d- RWB. That's a central role in a Amorim's system and neither Dalot nor Mazraoui can provide the attacking input needed for that role. I actually struggle to understand what Dalot bring to the table rather then availability. He's not great going forward, he's not great when defending. He reminds me of a very poor version of Phil Neville with the difference that Phil wasn't a WB. But that's an argument for another day
So that's 4 positions, at least 5 players (I'd say 6) that we need
Now let's have a look at no 10. We've got Bruno whose a top player and Amad whose not that far from being first team level. Zirkzee and Garnacho are good enough as cover/competitors, Mount is a wildcard if he can remain fit and Mainoo's future lay as a no 10. Then we mustn't forget that Sancho, Antony and Rashford are still on our payroll. Some might say that they will never play for us again. However they are still on our payroll which means that their salary is being paid by us. If we want additional funds then at least 2 out of 3 need to move elsewhere for a decent fee.
I repeat I like Cunha. However we've already got 9 no 10s (Bruno, Amad, Zirkzee, Garnacho, Mainoo, Mount, Sancho, Antony and Rashford). Unless we get rid of at least 5 of them for a fee then I do question adding another no 10.
