The Highbury hero is dismayed with his former team's lack of organisation at the back, and says they need to put in much more work on the training ground in that department
Seaman, a winner of three league titles and four FA Cups with the Gunners, believes that Arsenal need to be more focused on training defensively, just as they were in the George Graham era.
The former England shot-stopper is a big fan of young Polish keeper Szczesny, but he believes that the 21-year-old is being given far too much to do and those in front of him need to tighten up.
"In 1991, we trained so much on that back four," Seaman told Sky Sports News.
"Pat Rice [Arsenal assistant manager] was there so he knows what needs to be done. We trained and trained and trained and it worked, but at the moment the goalkeeper Szczesny is getting too much to do.
"He’s showing how good he is but I don’t like to see that. A goalkeeper for Arsenal normally has one or two saves a match and that’s it.
"But at the moment he’s keeping the scoreline down, not [keeping the team in the game]."
The Gunners fell to a 2-1 defeat to Tottenham on Sunday, meaning that they have been beaten four times already this season in the Premier League, and Seaman was bitterly disappointed with his old team's performance at White Hart Lane.
"It’s very frustrating," he continued.
"Performance-wise it wasn’t the best, but the result is the most frustrating part about it. It’s a massive game for the fans. It’s really frustrating to see what Arsenal are going through at this time.
"That [conceding 16 goals in the league] is obviously showing their weakness but you’ve got to train them and practice it.
"From what I see it doesn’t look like a lot of people know what they’re doing or know what position they’re supposed to be in.
"I’m sure it’s not like that in training but that’s what it looks like from watching it on the TV."
