They might win under probability, I don't see the need judging Arsenal from their previous performance last season besides they're doing great this season compared to last season. During last season Arsenal left the race so quick, they never struggled but rather they made everything look so easy for city boys, we can all agree Arsenal will not just back off so easily. From my view I expected more from Arsenal during the champion league match against Bayern, for crying out loud Arsenal made a big mistake drawing the match against Bayern at Emirates. If Arsenal never get the chance to defeat Bayern at Allianz they might face the premier league with so much force and energy cause it will be so embarrassing if Arsenal never get to win a tittle this season
Mikel Arteta's team was not very lucky in the first leg against Bayern yesterday. But I have a feeling that in the second leg they will be able to play more aggressively even though the match will be held at the Allianz Arena or Bayern Munich's headquarters. Because I think that Arteta's team has a pretty strong mentality even when they are facing their opponents. As a simple example, we can see how Arsenal made things difficult for Manchester City when they competed at the Etihad Stadium. And maybe something similar will happen at the Allianz Arena. But if Arsenal fails then I agree that Arsenal will fight harder in the Premier League with maximum strength. Because if Arteta fails in the UCL then they must succeed in the EPL. Although Liverpool and Manchester City may still be tough rivals for Arsenal.
Apart from all that, by the way, Liverpool is currently competing in the quarter-finals of the Europa League. And they were 1 goal behind by Atalanta in the first half.
