Wether Xavi was a good coach or not is open to interpretation. What matters is that he was a champion coach for us in very difficult circumstances. Champion and "not even decent" are two ideas that do not mix well for reasonable people.
For example and context, Roberto Di Matteo is considered decent coach worldwide(by all critics), just on the shoulder of winning a historic Champions league in a difficult situation too(won nothihg after and disappeared).
Dont think Xavi comes close in achievement except in deluded minds .
And If you placed Xavi ahead of Di Matteo in any ranking, then you would have crossed the line demarcating decent and good, after which is great, and we know Xavis was neither good nor great as a Barca coach. He never won a champions league to be considered "decent" enough.
He was a great player and a legend of immeasurable proportion for Barca, but as a coach, he was not great nor good and even to be labelled decent is arguable. Just like Diego Maradona and other great players that never achieved close to proportion of their status as a player.
