There will be pressure on Xavi once he becomes the new coaching staff of Real Madrid, he's a great coach but i think Real Madrid should want a more older coach that has experiences which keeps Klopp ahead, pressure will be much on him as the team will expect a quick change that should bring them back leading the La Liga table once again. Next season Madrid has a hope of winning a trophy, i don't think of them going both seasons without winning any trophy, i feel the need of them coming stronger.
Barcelona legend Xavi has nothing to do with Real Madrid. Real Madrid are parting ways with Ancelotti. His replacement is most likely Xabi Alonso. It's not that Real Madrid can't win trophies next season, but they have to accept that they are behind Barcelona now. The competition in the Champions League is already fierce. They are no longer among the top 5 favorites. Xabi Alonso's first task will be to define his own tactics and convince the players of this new game. If he doesn't manage the players well, he won't have an easy job with players like Vinicius and Mbappe.
