Wednesday's emphatic 5-1 win against an embarrassingly inept Arsenal can be seen as "proof of concept", it allows the Italian to continue with his low-intensity regime, until the quarterfinals at least.
The game looked to have lost its pace early in the second half before Bayern suddenly stepped on the gas to fire three goals past the English side.
"Normally, we are always where we need to be for games like that, but it is a completely different match", said Robben.
"I am not looking for excuses".
These players have risen to the occasion against Bayern before, beating them twice in recent years.
"Arsenal have completely disintegrated".
"We are a ******g shambles", he posted.
"I think a new manager coming in would certainly improve them".
Wenger's players initially seemed petrified in the face of that kind of finesse, and Bayern were too easily finding space in behind Francis Coquelin and Granit Xhaka.
"They may now realise that I was right all along".
But Neuer was quick to row back on the suggestion that Arsenal might be a soft touch.
Wenger's future may be "not a subject for now" but he was adamant Arsenal can beat a powerful Bayern team who, for all their reported stumbles, have still won 10 of their past 11 games and sit seven points clear at the top of the Bundesliga. We have an advantage to play the second game at home.
"It is a shock of course to lose at that level".
A rampant Bayern continued to poor forward and with Arsenal wilting under pressure, an inevitable fourth goal arrived in the 63rd minute, moments after the Bavarians had hit the bar.
But Robert Lewandowski restored the German side's lead after 53 minutes, heading in a cross from Philipp Lahm with Thiago Alcantara adding a third just three minutes later.
Lee Dixon has joined the growing list of former Arsenal players sensing manager Arsene Wenger will call time on his 21-year spell at the north London club after yet another rollercoaster season.
Former Arsenal defender Martin Keown told BT Sport he felt for his former manager.
Because of that run, Wenger has again seen a minority of fans calling for him to leave, with his current deal expiring at the end of the season. Yet again an bad performance in the first leg of the round of 16 tie saw the team blow the chance of progression in the competition before the second leg - let alone before the clocks go forward.
"I think if he announced today or tomorrow that he was stepping down at the end of the season he would then be revered as the legend he is at the football club".
Bayern then had more of the possession but the Gunners never let them take full control of the proceedings and looked threatening on the counter.
