Former striker Ronny Rosenthal has dismissed claims the club is on the slide. Rosenthal insists anything is possible with manager in charge. He told TMW: "I don't think a cycle has ended, English football is the most competitive in the world and it is natural that there may be a wrong season. There will be a Europa League to play and will be the protagonist. "It may happen that after so many years it's necessary to change, but that's not the case with . In my opinion it's more a question of the quality of the players. One player per department will be needed, this will be enough to return to the top 4 as early as next year."
