With an aggregate of 0-1, of course Bayern Munich fate is very much at stake in Leg 2. Playing at home is indeed an advantage, but considering that Tuchel problems are getting more and more complicated by the day. To be honest, Tuchel is not always wrong, sometimes his players make mistakes and are unable to play solidly. With the pressure of having to win totally, I think Lazio will try everything they can to win. With the situation being unstable for both coaches, players and Bayern Munich officials, perhaps we will lose them in the UCL this season to advance to the top 8.
It is not impossible that initially Bayern Munich was made a strong candidate to win the UCL trophy but with the problem of consecutive poor performance it was doubtful that they would qualify.
Thomas Tuchel still have much problem with current Bayern Munich performance, since losses in Champion League match first leg looks easily for Bayern Munich continue with losing trend. Last match defeated by not favorite team in Bundesliga from Bochum and Bayern Munich get huge pressure how difficult back to the higher standings with 11 points left from Bayern Leverkusen.
Bayern Munich's manager have forget awhile with bad performed in bundesliga and ask his players keep focusing on second legs match for winning above two goals if want secure spot in Champion League.
Lazio will not play more offensive and they know how much potential conceded many goals if their player focus on offensive than defensive area, how difficult face by Bayern Munich on second leg match and how much percent ratio winning for Bayern qualifying to the next round.
