It is the stupid Ole mantra "we will only sign young handsome british players" He actually tried to force this kid into giving up his nationality to play for England, just so he could play for United. You see.
Haaland, the son, is actually born in Leeds, in the same hospital his father lived in for many years, after getting his knee tore off by Roy Keane's dad during a baseball match. SAF worked at this hospital as a caretaker, where he first met and grew fond of a man named Carmine Raiola, a priest working to bridge the gap between the injured fathers and abandoned sons inside of the same hospital. I will cut this story short, but it all ended with a falling out between SAF and Raiola where a shoe were being thrown from one side of the hospital room where the fathers were, over to the other side where the kids were and yeah, it ended badly. Saying that to say this, Haaland would never in a million years play for United, not with all of that still going on.
