Arsenal boss Arsene Wenger has taken a swipe at Manchester United over their swoop for Monaco striker Anthony Martial.
Wenger is convinced United paid way over the odds for the youngster.
The Frenchman told beIn Sports: "What happened last night with Monaco, who sold Martial to Manchester United for 80million Euros, I've heard.
"Martial scored 11 goals in the French championship - that sums it up well.
"That means it's not the money that's missing at the moment, it's not the desire of investment that is missing, it's the number of players available who can strengthen the big clubs."
