Wenger has insisted several times that Sanchez will not be sold, although links with Manchester City continue.

Having played in the Confederations Cup up until the final on July 2, Sanchez was given an extended summer break which included missing Sunday's Community Shield penalty win over Chelsea.

Now Wenger has revealed the 28-year-old will miss Friday's Premier League clash at home to Leicester as well as the trip to Stoke the following weekend.

"Alexis will not be available," he said when asked about team news ahead of the visit of the Foxes.

"He has a little abdominal strain that he caught on Sunday morning in training, before he came to Wembley. He had a scan two days ago and he's out for a while.

"I don't know if it is two weeks or one more week, but he will not be available. I think he will not play at Stoke, yes."

Wenger admitted entering the new campaign without Sanchez is a blow for the Gunners but said he would not have featured against Leicester even if he had not suffered a set-back.

"For us Alexis Sanchez is a loss, of course," he said.

"But we have all the other players prepared in pre-season and they are all ready. It can happen in pre-season and anyway, I don't think I would have included him on Friday night. I don't think I would have started him."

Sanchez's initial return to training was delayed by three days as he had an illness but his extended absence from the team will only flame the fires of speculation over his future.

Wenger would not reveal whether there had been any concrete offers for Sanchez and said his close relationship with Paris Saint-Germain chairman Nasser Al-Khelaifi had no baring on the player's future.

Asked if any bids had been lodged for Sanchez, the Frenchman replied: "I can't tell you that at the moment. I just think we are not open - what I said to you many times - to any offers, anyway.

"It's a long time I didn't speak to Nasser, because it's certainly very busy to complete the transfer of Neymar and it's a long time that I didn't speak to him."

Pushed on whether he expected Al-Khelaifi to get in touch, he added: "No, no. I think if you read the French papers, they are on (Kylian) Mbappe's case to finish their transfer market."

After Arsenal's Wembley win on Sunday, Wenger admitted he was looking to trim his squad before the transfer window closes.

But he is no closer to shifting those deemed surplus to requirements as he believes many Premier League clubs are in the same position.

"No," he replied when asked whether any players are closer to departing the club.

"Yesterday I had the managers' meeting and was talking with the other managers in the other clubs. It looks like everywhere there is many, many players and a bit of congestion at the moment everywhere."
