The Sky Sports pundit and Arsenal's record goalscorer has named what Arsenal are missing to make their stadium a fortress.
Of course, the Frenchman is a veteran of Arsenal's formidable record at Highbury, a stadium that visitors got little from under manager Arsene Wenger, and which hosted some champagne moments in Arsenal's trophy-laden history.
Henry himself scored the very last goal in a competitive game at Highbury in May 2006, one of many goals that lead him to have a statue designed and erected at the Gunners' impressive new home.
But, despite some dramatic wins over rivals such as Tottenham and Manchester United at the Emirates, and a European triumph over Barcelona in 2011, the 60,000-capacity new stadium has also been the scene of some derby failings against Spurs and a number of Champions League defeats.
Henry claims it was a very necessary move for Arsenal to make to the 'new' stadium - at which he only played for one season in 2006-07 before a transfer to Barcelona in June 2007 and a brief loan return in 2012 - but that it has yet to see a "title moment" and therefore, Arsenal are struggling to make it a fortress.
It was in that 2012 loan move from the New York Red Bulls that Henry provided one of the Emirates' most treasured moments, when he settled an FA Cup tie with Leeds by scoring with his first touch in the last minute. But speaking to Ed Chamberlin for Sky Sports, Henry said: "I think Arsenal needed to move on, the club needed to be in a stadium like this. What didn’t happen yet, is Arsenal didn’t make it, so far, like a fortress.
“What I mean by that is that they still didn’t win the title here. It feels empty sometimes, like you’re always remembering the Highbury days. People will remember, when they think about the Emirates, the win against (Manchester) United last minute, the win against Barcelona here in the Champions League, but you don’t have a title moment. I think that’s the only thing that the stadium is missing."
Many Arsenal fans will agree that the Emirates will only truly feel like 'home' when Arsenal win the league title there.
