Look, I am pretty sure Ten Hag will bring in one or two Ajax players, but he'll look further ahead too. Frenkie de Jong would make a lot of sense and they're obviously trying to make a deal happen, and I am certain he will bring someone in from the current Ajax. Martínez makes most sense based on Utd's lacks (and his left foot), and Antony based on the most recent news could be an option as well. But it's mostly about people he really trusts and with Martínez there was a stint where he didn't (although I think that changed). In that trust sense, I wouldn't even be surprised by a Berghuis signing. But my point is that I think we will sign one or two Ajax players, not more, and that FDJ is an ex-ETH/Ajax player who seems likely at the moment.
I'm not sure if he sees De Ligt as a priority right now, even though he really admires him, I think he will focus on how to make a complete balanced squad first, and then improve on it after. In my opinion, De Ligt is better than Maguire and Lindelof, but I think Ten Hag would prefer to fix midfield first. It also depends on 'the leaders' in the squad. If Ten Hag sees Varane or Maguire as a real leader, he will not move for De Ligt. If he doesn't, chances increase. But Ten Hag looks a little differently at leaders than Solskjaer does, so we will have to wait and find out how he approaches this situation.
But at the moment I wouldn't be suprised to see us go for two CM/DM types. Based on Ajax he might go for both FDJ and Neves based on 18-19, but he could also like an anchor type and go for someone more sturdy. I honestly can't see him see McT as an anchor man, but with ETH you never know. But what I do know is that he likes 'depth' up front. He wants someone who can sprint ahead to catch potential through balls by the midfielders/defenders. That probably means he wants one of the center backs to be/get better at technical (stuff). At Utrecht he had Janssen, then at Ajax he had Frenkie, followed by Blind and later Martínez (together) for that role, and even spiced it up with Timber later (although that resulted in a more defensive and tall DM in front of them in the form of Álvarez). - Maybe that does mean at least one CB signing, because according to Ole Maguire and Lindelof are ball players, but I'm not sure if ETH sees them as such...
His midfield hasn't always looked the same, but he wants at least one midfielder who runs deep, too. That could be Donny joining the striker, could be a Bruno with more midfield duties, too. I wouldn't be surprised to see Bruno get a more Ajax-Ziyech type role on the left wing, but that's another discussion.
I do wonder if ETH really wants a new winger, though. I know about the Antony news, but with Sancho, Rashford, Elanga, Diallo and Bruno I am not completely convinced that will be his top priority in the build up. If Sancho and Bruno (and Diallo if not loaned out) act as the creative wingers (Sancho perhaps more of a hybrid option), Rashford and Elanga as the running deep wingers, you have an ETH forwards set-up at your disposal, except for a Ronaldo back-up if Martial leaves definitively. If I'm right about Bruno, I think AM might be more of a priority for ETH to have an option next to Donny/Bruno. Again, though, we will probably be suprised about ETH's utility of some of the players.
Okay so that was my thesis not answering the question. What follows is one that attempts to do so.
LCB: I'd still get Martínez. I get the Pau Torres links, but think Martínez fits more plans and is more technical. If Maguire leaves, Pau becomes an option for me, which would still be nice, with space to move Martinez to DM/LB occasionally. - Lisandro Martínez.
LCM: Frenkie. Dynamic playmaker that can help out in defense and control the midfield against tough opposition through his dribbling and composure. - Frenkie de Jong.
RCM: Neves is a more static playmaker that I think will be an asset next to someone like De Jong. While Frenkie moves around, Neves holds the fort while still moving play around and being able to hand the forwards some killer passes every once in a while. Not a defensive machine, but in my setup he will do enough together with Frenkie to get the job done, while bringing ManUtd's possession game up a few levels. If Frenkie does not come, I don't think Neves works and I don't see them as a plan A/B type deal at all. - Ruben Neves.
AM: I don't have a clear option in mind, but someone like Marcos Llorente could work very well. I don't want to see him leave but atm I can't think of another example to fill in this slot. Also don't think he wants to leave right now, but as a profile he rocks. - Marcos Llorente.
SB: This is a bonus option and I can't think of one yet, but Cancelo fills in this slot for City kinda, where there's a technical fullback who can fill in either side. Rensch was this at Ajax to some extent, but he stalled last season, so he is not close to being an option. I think AWB could still get his chance if he gets less creative responsibilities, but I understand the sentiment for a more technical/playmaking fullback to aid midfield, as well. If Martinez, FDJ and Neves all come, it's not a necessity, but the option would be cool. Perhaps that's a good reason to keep it a talent like Rensch for now, because I'm not knowledgeable enough about other options - nor the Utd youth system (or am not awake enough). I do think Shaw and Telles have a chance to improve under ETH though, but just to check - Devyne Rensch.
That would have the team look like this in my bollocksy strategy:
GK: De Gea, Henderson, other fellers.
RB: AWB, Rensch, Dalot if he stays.
RCB: Varane, Lindelof, Bailly and Axel if they stay
LCB: Martinez, Maguire, and those who did not leave.
LB: Shaw, Telles, Rensch, Williams.
RCM: Neves, McTominay, Donny, youth guy.
LCM: Frenkie, Fred, youth guy, Bruno.
AM: Llorente, Donny, Fred, Bruno.
RW: Rashford, Sancho, Elanga, Diallo.
LW: Bruno, Sancho, Rashford, youth guy, Martial.
CF: Ronaldo, Martial, Rashford, youth guy, Bruno.
Or:
De Gea; AWB, Varane, Martinez, Shaw; Neves, Frenkie; Rashford, Llorente, Sancho/Bruno; Ronaldo.
Subs: Henderson, Lindelof, Maguire, Rensch/Dalot, Telles, McT, Fred, Donny, Sancho/Bruno, Elanga, Martial.
The whole midfield might be a bit much, but oh well, I think Fred, Donny and Bruno can do a job there, but I am not sure if ETH sees them as BPL level midfield players. Bruno has quality, but sometimes he slacks in being available for the midfielders and I think Fred, Matic, McT, Pogba all suffered from that in many games too. ETH can do a job with him, but I would not be surprised to see him move to the wings on a more permanent basis, and put a 10 there who allows FDJ and Neves to create something for him, instead of the other way around.
