Arsene Wenger’s side came from 2-1 and 3-2 down to defeat Leicester 4-3 in their opening Premier League match.
But the Arsenal backline without Laurent Koscielny and Shkodran Mustafi came under fire for the defensive performance, and especially Leicester’s third goal from a corner.
Henry refused to solely blame the defensive display on the back three, saying the rest of the team need to apply more pressure on the opposition.
The Gunners’ club-record goalscorer thinks Arsenal haven’t made any progression from last season, and that they are still making the same mistakes at the Emirates.
Speaking on Sky Sports, Henry said: “You can talk about evolution or revolution at Arsenal, I call it stagnation.
“I watched the game against Leicester and I could tell you what was going to happen. When I go to the Emirates and I watch the game, it's 'Yes!' when we have the ball and 'No!' when the opposition does.
“Every time Leicester had the ball I felt they were going to score and every time we had the ball I felt we were going to score.
“People can have a go at the defence but when you play in a back three, it is what is happening in front of you that counts a lot. If you don't apply pressure well you will be exposed in a back three.
“What I saw, I have seen so many times. Arsenal came back into the game, Aaron Ramsey came on and Olivier Giroud saved the day. But I have seen that too many times.”
And Henry says he thinks the Gunners yet again will be caught out by the bigger teams in the Premier League.
“Are you always going to score four and concede three? At some point you will be found out.
“It was the first game of the season and, yes, some of the guys were new in the team. But based on how they played, I saw that too often last year. I didn't see any change.”
