It's little wonder some of Europe's elite might look to poach the Chile worldwide after Arsenal finished fifth in the Premier League last season.
Following the Gunners' 4-3 victory over Leicester City in their Premier League opener, the Arsenal boss delivered his update on the Chile global after the attacker was seen watching his team from the stands.
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. "He practised well today, this morning, had a good session for the first time because he had a little muscular strain".
'He had a scan two days ago and he's out for a while - I don't know; two weeks or one more week? Manchester City and Paris Saint-Germain are reportedly interested in the player, who has just one year left on his contract at Arsenal.
For us Alexis Sanchez is a loss, of course.
"(PSG) are looking for (Kylian) Mbappe, that's what I read in the papers. But we have all the other players prepared in pre-season and they are all ready.
"Arsenal fans want him to stay", the former Arsenal forward said.
Wenger also dismissed Chelsea's reported interest in Alex Oxlade-Chamberlain, saying he is still firmly in his first-team plans.
"I felt that to lose tonight would have been bad for us because we had such good preparation and to sit there in the morning and think we had lost at home would have been awful", he said.
Speaking after Arsenal beat Chelsea on penalties at Wembley, Wenger revealed he was looking to trim his squad before the transfer window closes, but he said no departures were now imminent. "I believe he will be a very great player".
