Because it will not be easy enough to compete in the championship position for Leverkusen, at least Leverkusen must be able to bring in some quality players to improve the team's strength to be better. Because Ten Hag will find it easier to organize and provide his tactics to more qualified players so that the Leverkusen team is not in a worse condition next season. I also hope that the Leverkusen team can still be a strong competitor in the Bundesliga even though Alonso is no longer coached.
Alonso has set the bar high at Bayern Leverkusen in the period he was the coach that the team's management and fans will be looking forward to seeing the team improve more. Ten Hang once did something marvelous with that Ajax young team some years ago, his credentials were in doubt when he was at the helms of affairs at Manchester United. I believe with the right players, he can actually achieve great things with Leverkusen.
