The 27 year old player has made clear he wants to join Arsenal and sources in Russia say the invitation to Arsenal officials is a gesture by Zenit to show they do want the deal to go through successfully.
Wenger, though, was attempting to concentrate on tonight's trip to Hull and banish the memory of the demons which, the Arsenal manager claimed, made his physically sick.
Arsenal lost 2-1 to Hull at the Emirates earlier this season, a result which shocked Wenger.
"I feel that on the day we were just not cautious enough. We were a bit too cavalier," said Wenger. "It was a big blow because if we had won that game we would have been top of the league. It was a massive disappointment.
"They were a complete surprise package and at the moment they take advantage of the fact that they started very well, they have 27 points and you would still think that 27 points would be enough to get out of a relegation battle. I think four wins would be enough to get them out of it and they are high enough up the table.
"I think they started free of expectation, they had quality and then they got a few knocks but how do they continue? The team has put the handbrake on a bit because the confidence is not exactly the same.
"But as well, in the game against us they played well but they had three shots of goal, scored twice and that cannot last for 38 games."
Wenger is hoping Emmanuel Adebayor can regain the form he showed last season when he scored 30 goals. So far the Togo striker has scored 11 goals.
"He has not had the same form," added Wenger. "At the moment, he is working very hard to come back to good form.He had dropped off a little bit, but that can happen sometimes.
"Ronaldo scored 44 last year, and it does not look like he will score 44 this season - because he and Adebayor had exceptional numbers.
"What is important is that he works hard and contributes to the team - if he opens the way [to goal] for other players, for me it is the same."
