Xabi will probably leave at the end of the year if he goes to Real Madrid. There is very little time left in the year and it makes no sense to leave the team now. Real Madrid will not let Ancelotti go before the end of the season anyway. Leverkusen has reached a completely different level with Xabi. We need to accept this and think about what a coach who takes Leverkusen to a higher level can achieve for Real Madrid. Real Madrid is currently losing to Arsenal in the Champions League. Maybe Xabi will be in Spain next year but the tactics he left behind will continue with Leverkusen.
Is it really certain that this will happen to Real Madrid and Leverkusen in terms of coaches next season? Because if it is only a rumor, I think it is possible that Ancelotti and Xabi Alonso will stay in their current teams for another season before they actually leave for another team. Especially if we look at the condition of the two teams this season, of course both of them still really need new tactics in order to find better results and that is regardless of who coaches them. And for this season, both coaches have also felt the pressure due to the difficulty of becoming champions in the domestic league and in the Champions League like Real Madrid.
