Hoffenheim is missing great opportunities, they haven't won a match for weeks. I feel sorry for them, they had a very high chance of being among the top 5 teams, but the point difference between them and their rivals is increasing day by day.
You are right there performance is too poor because there last 14 matches they have not been able to make any good impact however they lose 8 matches out of the 14 matches they have played and draw six matches what a bad performance by Hoffenheim, that's why they have not been able to advance on there league table, perhaps let's see how there performance will be on there match against Union Berlin, if they failed to win Union Berlin including there home advantage then I will no that Hoffenheim has completely lost form on this season because Union Berlin also has the worst performance on this season that's why they are still struggling close to the bottom of the league table.
Because there are Bayer Leverkusen and Stuttgart in the top four then yes, it makes competition in the upper zone in the Bundesliga standings this season become very difficult . Because after all, in fact strong teams like Leipzig also failed to maintain their position in the top four because Leipzig lost the competition with Dortmund. With such considerations then yes, I think it is still very reasonable for a team of Hoffenheim level not to be able to compete well in the top six in the Bundesliga standings because the competition has become very difficult . After all, at least Hoffenheim is also still in 8th position and yes, I think that is still a good position for a team like Hoffenheim.
