A number of Barca players have spoken out about the Fabregas saga over the last year, but Xavi's recent claim that the Arsenal captain is "suffering" appeared on the club's official website.
Arsenal could have attempted to contact FIFA to object to the 'tapping up', but Wenger does not believe the complaint would be successful.
"I don't think it's a sentence big enough to report a club to FIFA," he said. "The impression I had was that it wasn't respectful to our club or to Cesc. I don't make more than that.
"It has to stop, of course. If there is a transfer negotiation between two clubs, I don't think it is healthy if players come out [and talk] who are not concerned by it. Unfortunately, in this case, it has happened a few times. It will not contribute to sort any problem out.
"Xavi has no direct part to play in that story and I don't see why he should, unless he has an official job to do for Barcelona. I don't see why he can go on the [official Barcelona] website and make this kind of statement."
