Inevitably when Manchester United are mentioned, the price tends to go up. If all these CB's mentioned are available at such ridiculous prices, then let's give our own guys a chance, TFM, Tuanzebe, and even Garner has played in that position. My own opinion is that De Ligt looks the best prospect, and Tuanzebe will be a class player in time, TFM I'm not sure about, but as a defensive midfielder he could be useful. Garner appears to be groomed for that midfield spot, but I suppose could drop back into a CB position if needed during a match.
