I don't see any hope for Bayern Munich for taking over the table from Leverkusen, they have 8 points interval and with the current form of Leverkusen now Bayern Munich have to exercise patience this season and allow Xabi Alonso to finish what he has started, as for the Champions league Lazio are already taking lead and Lazio will see it as an advantage to qualify to quarter finals, the both teams seem to have equal performance but still Lazio have to put more effort despite they have won the first leg, the second leg will be a little bit difficult to win because despite Bayern Munich performance are fluctuating they don't joke with home game which I fill the can make it to quarter final.
As a team that always dominates the Bundesliga, I am sure Bayern will do a good job until the end of this season. so, Munich will not allow Leverkusen to easily move forward in the race for the title this season. even though the interval is 8 points, there are still 11 matches remaining. as a giant Bundesliga club, they have their prestige at stake if they let their rival team walk smoothly to break the domination that Bayern Munich has dominated so far. especially for Tuchel who said that he would do his best with his coaching staff until the end of this season. the rest, let the end of the competition answer the winner this season. so, Tuchel will not let Xabi Alonso progress smoothly. Moreover, there are still 11 decisive matches. in football, ups and downs can happen suddenly to any team, including Leverkusen even though they are currently in a positive trend. 11 matches, is a long match. It takes hard work for Alonso and his squad to break Bayern Munich's dominance. so, let's just enjoy every week what happens in the Bundesliga.
As for the Champions League, a 1 goal aggregate lead does not make Lazio safe. moreover, the second leg will be played at the Allianz Arena, Munich has a high probability of overthrowing Lazio with a landslide score. thus, Bayern has the potential to advance to the next phase. however, we cannot yet confirm this. moreover, I haven't gotten any information for these two teams. well, we will find out the results when these two teams meet in the second leg. so, let's just wait.
