Jamie Carragher believes that Arsenal boss Unai Emery creates confusion with his selections and tactics.
Emery has tried several combinations of players in the past few weeks, even changing formations game by game.
But results have not improved, with the club unable to buy a win in their current form.
And former Liverpool centre-back Carragher believes Emery must take a lot of the blame.
Speaking on Sky Sports, Carragher said: "Unai Emery hasn't adapted, he's created confusion. Confusion in the crowd and confusion for himself.
"The Southampton game summed up the 18 months of Emery, really. How many times have we seen them messing around at the back and almost conceding goals?
"If I think of Emery and Arsenal, and how they play, they score goals and concede goals. They play out from the back and almost concede goals.
"He's used more players than anyone. He's made more changes at half-time or before half-time than anyone. That's something you'd expect a lower team to be doing.
"I'm not quite sure what is really going on there, and that's why the confusion is being created."
