A 4-point advantage over Leverkusen does not mean Munich can win the Bundesliga title race, anything is possible because there are so many games to play. Munich must consistently maintain their performance if they want to keep their distance from Leverkusen, the tight schedule is a challenge for the coach in compiling the starting XI in each match.
The competition that Leverkusen provides puts Munich under a little more pressure than in previous seasons, they must avoid mistakes like when they were defeated by Mainz to win the title that Leverkusen won last season.
Four points is a fairly close distance and Munich themselves also know that they must be able to excel even more in the rest of this season so that Leverkusen can no longer catch Munich in the Bundesliga standings. But of course it will not be easy for any team in the rest of this season because in the second half of this season all teams will try to make improvements in order to be able to reduce the distance with each rival and be in a much better position than before. I am also pretty sure that Kompany is feeling a little more pressure at the moment because Munich are still quite close to the rivals who were able to win the Bundesliga last season.
