The midfielder played the full 90 minutes and captained the side in their 2-1 victory over Feyenoord on Sunday.
Despite signing with Ajax just a year ago, he reportedly pushed for a free transfer to Monaco, even threatening to stop playing.
The Dutch journalist began: "Can you say why you wanted to make a transfer to Monaco?" To which Henderson replied: "Based on what?" A back and forth then developed between the duo, which Mirror Football will now lay out in a transcript.
Journalist: "The coach has just told us you wanted to go to Monaco."
Henderson: "The coach has told you I wanted to go to Monaco?"
J: "Yes because you had a big offer."
H: "Because I had a big offer? That's not true."
J: "That's not true?"
H: "Yeah."
J: "Did Ajax tell you they wanted to sell you?"
H: "Did Ajax say they wanted to sell us? Well they were negotiating so I'd imagine they did yeah."
J: They were negotiating with Monaco?
H: "For a fee yeah."
J: Did you want a free transfer?
H: "No, no, they were negotiating a fee. But again, it's not about the details, I'm not giving you details. I know the truth, I know what happened, I'm not here to give you details. I'm just here to tell you from my side."
J: "You're saying it's not true, can you give details on your negotiation with Ajax?"
H: "No. I don't need to. You can though, it sounds like you can anyway. It was untrue."
J: "What was untrue?"
H: "Ninety-nine percent of it."
J: "Yeah but what, give an example?"
H: "What part, the bit before the game or the bit after?"
J: How did he (Ajax boss Francesco Farioli) convince you to stay?"
H: "It wasn't him. And he didn't need to convince us."
J: "Who convinced you to stay?"
H: "Nobody convinced us. Again you're going into detail, it's not about the detail."
J: "You know the details, give us the details, if you tell us it's not true."
H: "No, no, no. I don't need to. I don't need to sit here and defend. Because of my behaviour, in what way?"
J: "Because of you not being a captain on Thursday. Not celebrating the second goal."
H: "But you don't know the information. I've just explained this."
J: "Not thanking the crowd?"
H: "I clapped the crowd. I clapped the crowd when I went off."
