As the Gunners captain, the Frenchman introduced the late monarch to his squad in February 2007 but found himself stumped when facing strike partner Julio Baptista in the line-up.
“I had the opportunity to meet the Queen and I was nervous as hell,” Henry told CBS. “I remember thinking like I'm about to play a game or something.
“When you are at Buckingham Palace and you are meeting the Queen... I looked at Julio Baptista there and I forgot his name! I was like, ‘Who is that?’.
“Then I'm like, ‘Oh, Julio Baptista from Brazil’, then I went with Gilberto Silva, but I was just nervous. You know when you're nervous you want to go back in your own language? I don't think if I'd spoken French it would have worked...”
Henry added that, as a Londoner for so many years, he “only has respect” for the Queen and her work.
