Well it took Guardiola quite some many years to be able to win the Champions League despite he having one of the best teams in the world when it comes to great players,he always had great names but it took him several years in order to harmonize this team even in European competitions so all kudos to him,for me though any other coach would have won at least once the Champions League with these players in his disposal,just my opinion.I do believe Guardiola to be one of the best coaches out there but I think it took him a lot of time to win a Champions League trophy with all these great players,nevertheless the Champions are never judged so let's see the next upcoming season.
