All coaches need strong support from management to bring in players who suit their coaching characteristics, Pep Guardiola is a coach who has good qualities and he also has experience, Pep Guardiola has shown enough proof and no one doubts him anymore.
Likewise with Xavi Hernandez, who brought Barcelona out of its downturn when he first arrived, but now what is happening is not entirely Xavi's fault because management is not providing sufficient support for Xavi to bring in quality players.
We shouldn't just look at the results that Barcelona got, but overall their performance has really decreased compared to last season and I think with Barcelona's current quality and performance they are not worthy of competing in the UCL this season, I think Barcelona will not go any further in the course of the UCL this season.
Different conditions make the way of working and the results will be different too. Pep is supported because they have unlimited resources until now so Pep can do whatever he wants to Manchesrer City including reshuffling again and again but the difference occurs with Xavi here where he is indeed supported but his resources are inadequate so that his support is only what he can from Barcelona because they do not have enough resources but the demands of the fans and management are always excessive actually for Xavi because he is demanded by the fans and management. have sufficient resources even until now their financial situation seems very lacking but the demands of the fans and management are always excessive actually for Xavi because he is required to perform perfectly in improving Barcelona's performance with minimal financial problems that make him unable to do much to make the changes he wants.
This is a differentiator that makes the results will also be significant in the end and I agree with what you said because with this seeing the situation that happened Pep and Xavi cannot be compared just like that because even though they are both coaches of big clubs but the current situation is very different.
