Arsenal great Tony Adams has taken fresh aim at the club's transfer policy.
The former Arsenal skipper has questioned two of his old club's other recent moves.
They opted to sign Cedric Soares as another right-back option for Hector Bellerin.
Adams told Stadium Astro: "Cedric, is he better than [Hector] Bellerin? Have you made an improvement there? Or are you telling me we need two?
"Get rid of two and get a good one. You always bring players in better than the ones you've got or don't bring them to the club.
"And I go back to it again, Martinez, [Bernd] Leno, for me that is a massive mistake. I can't tell you.
"If I'm the owner of a club I'm looking at my sports director and saying, 'If we have any desire to win the league, you need two goalkeepers at least'.
"You've got two goalkeepers, you've got Leno and Martinez, good. You get rid of one and you get inconsistency, that's what you get."
