@shogun47 I believe that they’ll need to dip in the January transfer window asap to save their season and the most logical buy would be is Sancho because they’re tailored for each other. Furthermore if they decide against buying or loaning player’s then their season will only get worse hence I hope that they can loosen their purse strings and immediately make some quick deals.
But I think history is helpful to look at here as it tells me that winter transfers don't work out that well very often. Clubs can get lucky of course and maybe a player like Sancho is a good idea as you suggested. Both know each other and I don't know what Manchester United's position is because of Sancho and whether they would loan him out. But the situation for Sancho is bad, Manchester United doesn't give him play time when ten Hag is the coach and Borussia Dortmund needs to solve a few problems rather sooner than later. Maybe this is one of those transfers in winter where I would say that this could play out well for all parties involved. But usually I am not a big fan of winter transfers other than filling some gaps.
