The last games this year were supposed to be won by Schalke. Augsburg, Freiburg and Bielefeld. These are usually the games that should mean 3 points for each game. But with the current performance this will mean 3 points for the opponents.
If you play like yesterday against Leverkusen, they have to be happy if you get one or two points from the remaining three games this year. Nothing at all fits in the team at the moment. If there isn't a major change at Schalke during the short winter break, then the next traditional club will end up in the second Bundesliga. And as the financial situation in Schalke is, they could then take the same journey as 1.FC Kaiserslautern did.
Schalke 04 is in very poor form now. I don't remember the last time they won a match. I personally like this team. I watched the first Bundesliga in 2017. The Schalke 04 team performed very well that season. They need some good players in their team. And first of all they need a coach who is enough experienced and skilled. Otherwise they will not be able to perform well.
