'I always said the fact that we didn't find an agreement previous year doesn't mean the player will necessarily leave.
"We've lost Mustafi for about four to six weeks", Wenger said.
On the possibilty of Arsenal selling Ozil, Wenger said: "We have envisaged every solution, it is possible we might sell in January". "It is not happening at the moment" - and Merson's return to football with fourth-tier Welsh club Caerau of Maesteg - "We talk about professional football here".
"When you don't have the World Cup, you focus on your club".
Wenger added that Germany defender Shkodran Mustafi will not be fit until after the next worldwide break in November while hoping Laurien Koscielny will step in.
Alves was up against Sanchez on worldwide duty this week when his Brazil side beat Chile in a World Cup qualifier which saw Sanchez's side crash out of the competition. Watford play good football. The England defender spent last term on loan at Middlersbrough and has only made one appearance this season, against Doncaster Rovers in the Carabao Cup, but Wenger is looking forward to his progress.
Wenger might have given them an opening after admitting there is possibility that the two could be could.
"I didn't want to speak to him much [at full time] because I know how tough it is and also because I didn't want for people to interpret things in a way that would have put my professionalism in doubt".
"He doesn't have to leave Arsenal to get to the World Cup. I will always appreciate him and I will always wish him the best wherever he goes".
"If he keeps playing as he is he will go to the World Cup".
Wenger then suggested a tweak to the Christmas programme.
"You wouldn't want to sacrifice an evening with the family".
