Sanchez has been tracked by Manchester City, his preferred destination, with a move to Paris Saint-Germain now looking less likely. "I don't know if it is two weeks or one more week, but he will not be available".
The 28-year-old's future has also been continuously speculated about, with Sanchez still yet to put pen to paper on a new contract, although reports on Wednesday suggested that potential would-be suitors Paris Saint-Germain had ended their interest in signing him.More news: Guam Stays Calm, Dismisses North Korea Threat
Asked if any bids had been lodged for Sanchez, the Frenchman replied: "I can't tell you that at the moment".
"For us, Alexis Sanchez is a loss, of course", Wenger said, adding that he was unlikely to have included the Chilean worldwide in Friday's starting line-up regardless of the fresh injury. "But we have all the other players prepared in pre-season and they are all ready".
However, Wenger seemed convinced that Sanchez - who is in the past year of his contract - will be going nowhere this summer.
Speaking after that latest clash with the defending top-flight champions, Wenger, who will not be able to call upon the services of the suspended Laurent Koscielny, said that Ozil only had a "little chance" to feature against the Foxes and that Ramsey could also be lacking the requisite fitness. "That is a continuation of what I said at the end of the season".
