Alonso got consistent performances with Bayer Leverkusen throughout the season and his results would have been even more valuable had he been able to win the EL final. Those coaches who can achieve long-term stable results are valued, if Alonso doesn’t achieve anything with Bayer next season, the attitude towards him will also change, they will say that he was just lucky, or even regarding the final, a strong team could beat Atalanta, which means luck also played its part role for Alonso.
Alonso has done a very extraordinary job and is able to make history with Bayer Leverkusen. For next season it is certainly not easy for Alonso to be able to do the same again because the challenges will also be more different. In my opinion if Alonso fails next season it will definitely get a different assessment but that is something normal. And it looks like Alonso will not be disturbed by it and maybe he is ready to leave if it's not needed anymore. But the brilliant historical records that were created were difficult to make by others even that would not happen in the next half century.
