Henry introduced the boxing superstar to the Paris Saint-Germain striker and they engaged in conversation despite the language barrier.
The 22-year-old replied: “My English is so good, you can talk great.”
And AJ – channelling Del Boy – chimed in: “My French is good as well. I say, Hola, ¿cómo estás?”
The three of them all burst out laughing. ‘Je suis je reste,’ as Mr Trotter might say.
As the conversation continued, they discussed Kylian’s appearance on the cover of FIFA 21.
AJ is also in the game within Volta football and Henry is playable as an Icon, though upset former Arsenal and Barcelona striker Henry by admitting he sometimes plays as Real Madrid.
Henry asked Joshua: “Did you ever think you were ever going to be in the game one day?”
Joshua replied: “Never in my life. Even though I love football – this is my first passion – I never could imagine being in the game.”
Mbappe concluded: “It’s crazy, a boxer in a football game.”
In the present day, Joshua is currently in the gym preparing for his upcoming fight with Tyson Fury, while Mbappe is one game away from the Champions League quarter-final.
He scored a hat-trick at the Camp Nou in the first leg of the last 16 game and PSG are favourites to progress at the expense of Lionel Messi and co.
Henry, meanwhile, is looking for a new job having decided to leave MLS side Montreal.
