Wenger has also denied reports that Sanchez, who was left out of Arsenal's pre-season tour squad to rest after international duty, was in Paris last week to meet with PSG officials.
The Arsenal boss remains adamant that Sanchez is not for sale despite having less than 12 months left on his current contract and the genuine threat he could walk away for free next summer.
"No, I don't think he was in Paris," Wenger told reporters at his latest press conference, as reported by Arsenal's official website.
"I read L'Equipe in the last three or four days. It has moved from Sanchez to Neymar. Today they speak about Neymar, three days ago they speak about Alexis. They need as well, like you [reporters], subjects," the French coach added.
On the subject of PSG not likely signing both Sanchez and Neymar in one summer, he commented, "No. They cannot get Sanchez so they go for Neymar.
"My mind has been made up for a while now. I think I've made it clear a few times that he is not for sale and this is my stance."
However, while Wenger may be claiming a personal victory because he thinks PSG have moved on to Neymar because of Arsenal's hard line refusal to sell, a different version of events is suggested by the Manchester Evening News that brings Manchester City back into the picture.
It is suggested that Sanchez is deliberately pricing himself out of a move to PSG after demanding excessive wages of £500k-per-week.
It is a figure the former French champions are seemingly unwilling to pay and the gossip claim is that the player is hoping it puts pressure on Arsenal to accept a £50m bid from City. Sanchez previously worked with Pep Guardiola at Barcelona and is thought to be keen on a reunion.
