When 80% of your signings turn out to be flops, it's worth considering if the problem is with the club, not the players. Especially when they did very well before coming here, and go back to doing well after they leave. How many times has this happened at United? How many dozens of players have we signed after they were great at Dortmund or wherever, only for them to fail here, and then they bounce right back when we sell them on? It's so exceedingly rare that one of our big signings actually succeeds at this club.
