Arsenal boss Arsene Wenger has confessed problems with their transfer policy in recent years.
Wenger, speaking on SFR Sport, revealed Arsenal could've signed Kylian Mbappe before his emergence at AS Monaco.
And the Frenchman admits similar problems arose regarding Chelsea midfielder N'Golo Kante and Atletico Madrid star Antoine Griezmann.
He conceded: "We can improve our recruitment.
"When we talk about Mbappé, we could have had him sooner. Players like Griezmann or Kanté were possible for us.
"We missed them, not because of our financial limit. We need to be faster when players are not on the lists for all clubs."
