Being 1 or 2 goals behind is not a difficult thing to overcome and I don't see too much of what Bayern did in the round of 16 when they managed to win over Lazio in the second leg, I think it was appropriate.
Bayern has much stronger strength and mentality than Arsenal, so overall Bayern is slightly favored in this quarter-final regardless of what happens to the Bayern team in the domestic league.
There will of course be fierce competition because Arsenal is not a weak team, but we also have to make realistic predictions to place bets and for me Bayern will be able to win over Arsenal.
Bayern has significantly more experience in the Champions League, which will play a significant role at this stage. I think that it will be very difficult for Arsenal to play away, they need to count on the first home match, and if they fail to beat Bayern at the Emirates, then it will be difficult to count on the sucsses in return match.
Arsenal should take advantage of the fact that Bayern's defense is not the best this season, and Arsenal's attack shows very high performance in some matches. But in this pair, I certainly give the advantage to Bayern. And if we compare coaches, Tuchel has more experience in the Champions League than Arteta, so Bayern also has an advantage here.
