Things are a bit more difficult for Schalke, of course. They are at the bottom of the league and will have to work hard to get out of this position.
Schalke in season 22/23 can't compete with other top Bundesliga teams, they are stuck at the bottom of the rankings having only managed to get 9 points so far (out of 15 matches they won 2x - drew 3x - lost 10x). Schalke will face Werder on January 14, in their last meeting, Werder managed to win 2-1 and Schalke have a chance for revenge.
They need to make good player transfers. Staying in the Bundesliga is not easy because many teams are very strong. Schalke, Bochum and Stuttgart are the teams that are in the relegation pot. They must have spent this break mostly getting ready.
Stuttgart - Bochum - Schalke still has a great chance to get away from the relegation zone because they have only played 15 matches out of 34 matches this season, so there are 19 more matches they can fight for. I'm not really sure that the performance of the three (bochum - stuttgart - schalke) will improve for the better, but the competition for the mid-table and bottom of the Bundesliga is very tight.
