A lot of people trust Xabi Alonso, I don't think there was ever a problem about trusting him. What I even suspect is that there is too much expectations from him which is the biggest challenge he will face as Real Madrid coach. A lot of people are expecting him to do the same magic he did at Bayern Leverkusen, forgetting that those are different leagues with different style of football. In conclusion, I believe that Xabi is a great coach and a wonderful choice by Real Madrid but they have to give him time to build his team before expecting any trophy from him.
Trust issues coming directly to managers that are incompetent. Xabi Alonso have not shown any sign of weakness and this have become something everyone have thought about. A manager that's incharge of Real Madrid, there's a whole lot to acknowledgement towards his duties and position in the club. Bayer Leverkusen brought Xabi Alonso into limelight when they appointed him as headcoach, he changed the narrative and history of the club in just one season incharge, he brought the very best performance from the club and today, he's having to manage one of the best performing team in Europe.
