I think it's normal that when time is running out and the concentration of the players is starting to break down a little bit then it's certain that the tension will be lowered a little bit because it would be painful if a goal is scored at such a crucial time.
The 0-0 score is unlikely to change but indeed as long as there is still time then all possibilities still occur even though this is clearly still a loss for Leverkusen especially for this match they are playing at home which will definitely be a pity if they only get 1 point but I think it's still good enough.
VfB know they are struggling in attack so they will definitely buy more time now so that 1 point can be obtained.
Leverkusen's efforts to stick to Leipzig have not succeeded because the squad coached by Xabi Alonso had to be satisfied with 1 point in the 9th Bundesliga match this season. Leverkusen is 4 behind Leipzig and Bayern Munich who are above them in the rankings. I am even sure that other teams will be able to shift Leverkusen's ranking if they win the 9th match. The opportunities are there for Union Berlin and also Freiburg and Eintracht Frankfurt to take advantage of this week's matches to improve their rankings in the standings.
