The 31-year-old has also called on the club's board to back the manager by showing their ambition in the summer transfer market.
"I would say we could aim for Europe next season," he told the Express & Star. "Definitely for next season it's possible.
"If we can keep our bad spell very short then we have a good chance to finish properly in the top half of the table. The manager has the experience and we have the potential in the team.
"But you have to bring that potential onto the pitch as well and we learned a lot last season about what we have to do to be successful.
"If we can keep our focus for longer periods for next season there is a massive chance to get big success.
"It also depends on the chairman and the board and if they want to continue and increase the success."
