Former Arsenal striker John Hartson says Unai Emery's assessment of the loss to Eintracht Frankfurt was "delusional".
Emery said his team were in control of the match before a short spell allowed Frankfurt to seal a 2-1 win.
"To me, it sounded a bit delusional," Hartson said.
"It sounded like he's hiding from the reality of his team is not quite good enough, the players are not performing to the level they should be. Three out of the back four, I wouldn't even have in my team, I don't think they're good enough.
"When they were 2-1 down, they didn't bring [Nicolas] Pepe or [Alexandre] Lacazette on. If they had got on, he's probably worried Frankfurt would break away and make it embarrassing. He was worried more about shoring up defensively. The proof is there, the players are on the bench with the scarves around their face.
"I know he's trying to protect his players but if you perform like that, I wouldn't want to go face my manager or my team-mates in training. That performance was nowhere near good enough."
