The legendary Gunner doubts his former club can get back into the title race.
Joel Campbell had fired the Gunners ahead at the Emirates on Wednesday night, but goals from Wayne Routledge and Ashley Williams flipped the game on its head and, with it, possibly the North Londoners' hopes of a first league crown since 2004.
Boos echoed around the stadium at full time and a host of Arsenal players looked visibly deflated at the final whistle, with the hosts missing a glorious chance to move to within three points of Leicester City, who dropped two points the previous night.
Henry won the competition twice in his hugely successful spell at the club, and the legendary French striker says that the current generation's body language does not inspire confidence that they can still win this title.
"Wednesday’s result was a massive disappointment for Arsenal but I still do not like to see the players lying down at the final whistle," he told The Sun.
"There are still ten games to go, and 30 points to play for, so they need to send out a strong, positive message. Those players have to pick themselves off the floor, stand up and fight.
"Despite their recent poor results, Arsenal are still in with a shout in the title race. But the way they are playing at the moment does not tell me that they are going to win it."
Luckily for Arsene Wenger's side, second-placed Spurs - three points clear of Arsenal - lost as well that night, leaving Saturday's North London derby finely poised.
If they are to win the title, Arsenal need a swift response starting at White Hart Lane. Defeat might well end their hopes for another year.
