Manchester United legend Gary Neville has slammed their transfer policy.
United have spent fortunes this summer to sign Falcao, Angel di Maria, Daley Blind, Ander Herrera, Luke Shaw and Marco Rojo.
Neville said: "It's not the way I would expect United to go about their business, I thought it would be more controlled.
"I can't work it out and I know I worked with Danny Welbeck last week [with England], but it's odd. I have to admit I thought the Danny Welbeck sale was a strange one, but that's just me.
"Of all the prices paid this summer, there are right backs and left-backs galore who have been bought for £14m, £15m, £16m?
"How have Arsenal got him [Welbeck] for £16m? I can't work it out. It has helped out a competitor because Arsenal are the team they are fighting for fourth possibly.
"I am struggling to work out the logic, I can't understand it. It's odd in two or three ways.
"Falcao tipped them over the edge, it surprised and shocked everyone. How he gets them in that team I don't know. How they get Rooney, Di Maria, Robin van Persie, Falcao, Herrera, Januzaj and Mata into that team I don't know."
