The Gunners boss said in a press conference that the Chilean global has an abdominal strain and could be out for one or two weeks. "I just think we are not open - what I said to you many times - to any offers, anyway".
"He had a little abdominal strain that he caught on Sunday morning in training, before he came to Wembley".
Arsene Wenger insists Arsenal have had no contact with Paris Saint-Germain regarding a deal for Alexis Sanchez and reiterates that it is "possible" that the Chilean forward could yet choose to sign a new deal at the Emirates Stadium.
"It's a long time since I spoke with Nasser because he was certainly very busy to complete the transfer of Neymar", Wenger said.
With Arsenal failing to qualify for this season's UEFA Champions League, Sanchez, who was Arsenal's top scorer in the league with 24 goals last season, has been heavily linked with a move away from The Emirates although Wenger has repeatedly said this offseason that the Chile global is not for sale.
"Plenty of uncertainties about players who didn't play against Chelsea - Ramsey, Ozil, Mertesacker. I don't think I would have started him". I remember watching him at Bournemouth last season and he looked angry.
"He will not play against Stoke".
"(PSG) are looking for (Kylian) Mbappe, that's what I read in the papers.
"Yesterday I had the managers' meeting and was talking with the other managers in the other clubs".
The final player who could miss out on Friday is Mesut Ozil as Wenger has confirmed the German playmaker is still feeling the effects of an ankle injury that kept him out of the Chelsea game at the weekend.
But the Frenchman wants to add more quality as Laurent Koscielny and Gabriel Paulista continue their struggles with injuries.
