Reports had claimed that Wenger's patience with Sanchez had finally snapped last week.
Ozil was absent from Arsenal's 3-1 defeat at Liverpool on Saturday and although the German star has returned to training, club gaffer Arsene Wenger doesn't believe he is ready to face Bayern.
"Wenger is a manger with a lot of experience and more experience than others and I'm sure he will be able to react, to manage the situation".
The Gunners certainly have an uphill road to climb as they seek to turn the tables on Bayern, who have qualified for the Champions League semifinals in each of the last five seasons.
Tales of a training ground bust-up appeared across the board at the weekend.
According to the "invisible wall" "the time has come" for Arsene Wenger to step aside for a new manager having spent more than 20 years in the dugout.
Yet when his side had been outplayed and looked toothless at two goals down after 45 minutes, Wenger evidently had no option but to bring on the livewire Chilean at halftime.
Now the club hierarchy has raised questions over his attitude.
Sanchez was left out of the starting line-up at Anfield but came on and set up a goal for his side in the second half as Arsenal lost 3-1.More news: Bone bruise, MCL sprain to keep Kevin Durant out indefinitely
Alexis Sanchez would be incredible at Chelsea, says Stan Collymore.
The match did prove to be brilliant.
And he also believes a match like this could be the flawless opportunity for the Gunners to come roaring back into form.
Gilberto won two FA Cups during a six-year spell at the London club and was part of Wenger's Invincibles team that swept to the 2003-04 Premier League title without losing a match. "I have a good relationship with him and of course a lot of respect because not all the managers would be able to do what he did here in this club".
While Sanchez deserves to start, one player who could do with some time on the bench is Paul Pogba.
"We did go direct in the first half".
His contract expires in 2018 and Arsenal will struggle to convince him to renew if they fail to finish in the top four. Mesut Ozil has had flu and is not expected to be fit for tonight's game.
The Gunners are trying their best to hold on to the star duo but sources reveal that the Chilean has now chose to wait until Arsenal's top four finish is guaranteed before taking a final call on his Arsenal future.
