Wenger said: "I've not lost interest in him (Henry). He's still coming to practise with us.
"Our relationship is very close but, at the moment, I think he has had a second spell at the club that was very successful. You have to be cautious that it's not one time too many.
"I have not completely ruled it out but I haven't spoken about it with him at all."
Asked directly about Villa he said: "Any interest we have in any players has to be kept secret at the moment. I cannot come out with any names."
