Super agent Kia Joorabchian has taken aim at Arsenal's former chief scout Sven Mislintat.
Mislintat was appointed in November 2017 before moving on to become Stuttgart's sporting director in February last year.
Among the players signed under his watch were Matteo Guendouzi (£7m), Lucas Torreira (£25m) and Sokratis (£14m) - all of whom could leave Arsenal this summer.
Joorabchian told talkSPORT: "People forget about the previous guy, Sven.
"He made a bunch of, I don't like to use the word, but, cock-ups with players he brought in at very, very large numbers."
Mislintat is now sporting director of VfB Stuttgart, which he helped guide to promotion last season.
