It's normal for coaches to decline, and that's normal in football. That happened because maybe the style of play is no longer suitable for now because there are many new coaches who carry the style of playing modern football. But in terms of quality, we cannot doubt the quality possessed by a Kose Mourinho, he is one of the coaches who has ever existed in the world of football.
Jose Mourinho is a coach who already has a lot of experience in coaching football teams so there is no doubt about his quality. But this also includes the whole team where the players also have to be really fit and good in order to win the match, because Bayer Leverkusen, who became the team against AS Roma in the semifinals of the Europa League this season, is also not in bad condition so Jose Mourinho has to able to give the right direction to his team before the semifinal match begins.
Alonso without doubt has done exceptionally well with his Bayer Leverkusen side and are still very much in contention to win the UEFA Europa League competition.
But when you face a club that's managed by Jose Morinho who is a specialist in playing mind games before major games and knows how to perfect his tricks to get what he wants in matches of this magnitude then you gotta device means of overcoming him . I think the game will be a very close encounter but I expect Jose Mourinho's Roma to progress to the final
