Manchester City hosted the Gunners at the Etihad Stadium on Sunday afternoon in a huge clash for the top four.
In a scintillating affair the Gunners twice came back from a goal down to secure a 2-2 draw and all but seal their top three place.
It could have been much different though, as City gifted Arsenal their first goal after some calamitous defending from Gael Clichy and Hart handed them a cheap corner.
The England goalkeeper was seen laughing at that mistake and Henry was not impressed by it.
“The reaction of Joe Hart - why are you laughing? Why are you laughing? You gave them a cheap corner,” he told Sky Sports.
“I can assure you, I played with Jens Lehmann, if you do that to him he would've grabbed you by the collar of your neck and let you know what he thinks about you.”
The attitude shown by Hart is somewhat concerning but it is a clear indication of the issues City have had this season.
England will surely be concerned, too, with Hart set to be their number one goalkeeper at Euro 2016 this summer.
The Three Lions will need everyone at the top of their game if they are to be successful in that tournament and they will be hoping the goalkeeper can show a better attitude than he showed in this incident.
