Sure a 60M player CAN be a punt, but you're much more likely to hit on a 60M player than a 2M player. The problem with your Foyth theory (2 payoff, the other 3 need to be sold) is that at a low initial purchase price you're probably going to have trouble selling them if they don't pan out. Then you're stuck with their salaries on your books,
At least with a Di Maria, Man U could still sell him. They take a loss on the transfer fee, but someone else still values him enough to pay him and take him on.
I get the corresponding argument but I'm with you here, especially with the previous example of Angel Di Maria.
it's like saying we have a AM slot open and can afford both N'Jie and Messi. But we shouldn't sign Messi as he's technically still a punt.
Scouting and Values are there for a reason but all transfers could not work. Appreciate we're arguing over unproven players though
