No, I wouldn't. But I would say that there's no fukking way we're going to bring in any of the top 10 keepers in the world, according to fourfourtwo:

And I would definitely NOT agree that Martinez and Pope -- allegedly two of the top ten greatest keepers in the world -- are better than De Gea.
Let's just go through that Top Ten:
We're not bringing in Alission or Courtois, full stop and end of.
We're not bringing in Ter Stegen, who wouldn't be that much of an upgrade on De Gea anyway.
Pope is a solid keeper and definitely one for the future, but he's not better than De Gea today.
Ederson...he's not leaving City for United.
I haven't seen that much of Sommer, but I'm happy to concede that he's vastly superior to De Gea...but he's not leaving Bayern for United either.
Neuer...there's no doubt that he was once superior to De Gea. But there's also no doubt that we are not we're bringing in a 37-year old keeper coming off a serious injury.
Donnarumma is not leaving PSG. But let's concede him too.
I would not swap out De Gea for Onana.
I would not swap out De Gea for Martinez.
So, where would I rank De Gea? Hard to say as I don't watch every league around the world, but easily in the 15 if we're going to downplay his ability as much as possible.
Apart from Donnarumma I haven't heard of any outstanding keepers in the French league. Maybe there are some great keepers in the Buli and La Liga apart from Bayern's two keepers and Courtois and Ter Stegen in La Liga, but none come to mind as obviously superior to De Gea. There might be a gem in Serie A. There are some pretty decent keepers in the MLS and Liga MX, but let's rule those two leagues out altogether as being irrelevant to this discussion.
So going back to the prem let's start with Pickford, as it really is time for him to move on to a club which competes for trophies. Pickford is a solid enough keeper, but he is in no way an upgrade on De Gea and at least I would say not up to De Gea's level. Raya is solid, but he's not an upgrade on De Gea and is clearly inferior, as is Pickford, as a shot stopper. I'm not having Ramsdale either, any in event even if you believe he's superior to De Gea (not saying you are) he's not leaving Arsenal for United. Lloris, Sa, Sanchez...no thanks. Bazunu is an intriguing prospect who's not better than De Gea today, but in a few years might be as De Gea goes into his mid 30s. But we're not talking about the long term, which will come and there will be a day when De Gea will have to be replaced...we're talking about next season. For all the stick De Gea takes on the caf, not a single name of any credibility -- for example, we are not bringing in Alisson or Courtois -- has come up that demands we shitcan De Gea to sign that keeper.
