I don't think Xabi Alonso's proposed departure from Bayer Leverkusen at the end of the season is certain as the young Spanish manager is yet to publicly notify everyone about his next move
If Xabi Alonso leaves Bayer Leverkusen, then this will definitely be Bayer Leverkusen's final journey to become champions in the Bundesliga because the chance of winning will not happen a second time with a different coach. Xabi Alonso now knows the strengths and weaknesses of every player that Leverkusen has, so this coach is able to provide the right position for his players to bring victory. It is not certain that a new coach will be able to do what Xabi Alonso did.
No problem. As long as bayern leverkusen will be winning a trophy and what's wrong with it? the fact that if leverkusen was rarely winning the trophy. It was also helping the club to get the momentum again. Leverkusen is also under agreement with xabi alonso to let him leave from the club as long as the club who tried to sign him
I think that's not a serious problem if xabi will decide to leave from the club. Leverkusen may not able to find someone who will able to perform as good as him but this club can still win trophy this season despite the possibility for xabi to leave from the club.
The agreement has been fully explaining about what condition that leverkusen should agree when xabi decide to leave from there. I think that if you can find that on the various news regardting the agreement between xabi alonso and leverkusen.
The new coach obviously has different gameplay and strategy for the club. Xabi can at least give leverkusen some trophies before he will leave from the club.It has been a half and one year xabi being a leverkusen's coach and everything changed under him.
