in the second leg, I'm sure Bayern won't play slowly like in the first leg against Lazio, so far Bayern are still the favorite team in the Champions League, Tuchel just hasn't found the best strategy to maximize Bayern's attack line, apart from that, Harry Kane also doesn't seem to have adapted yet good with the strategy given by Tuchel.
I just hope that Musiala will be moved to the right wing midfielder because he is better there while Muller should be in the left wing position, Sane should be on the center wing to help the attack and defense more quickly, Lazio has a good defense then Bayern have to be more creative.
Losing one goal on the first leg, its not possible for Bayern Munich will playing with slowly rhythm and more aggressive for scoring as many possibilities goals in the early minutes. I don't think any wrong position with Jamal Musiala and he can plays well as attacking midfielder or Thomas Tuchel moving him as left or right winger position. But most effective with left winger side filled by Leroy Sané and Thomas Mular position as right winger.
Its more help with Lazio will playing more defensive on second leg because they have on comfort position after one goal capital, the draw result match on second leg is more enough to help Lazio qualify to quarter final of Champion League.
