We talk about 4 points a lot, but Bayer Leverkusen, which is 4 points ahead, has one game too many. If Bayern plays its missing match, the point difference may decrease to 1 point. Bayern is a strong team and they have the strength to continue the championship race with Leverkusen until the last match.
We can't predict which team will win the league title this season too early because Bayern Munich can disappoint with their performance, they have lost match this season, while Leverkusen has not lost any of their game. The Bundesliga will have many challenges this season, if Bayern Munich win their missing match, i don't think the one point difference will still make Bayern Munich so strong to become the championship this season. This is because Bayern Leverkusen also has strong players and they are performing very well at the moment. Leverkusen will continue to lead the league if they win their remaining games. All I can hope for is that Leverkusen should breaks Bayern Munich's record this season and stays at the top of the league till the end of the season, to become the Bundesliga championship.
