Of course Barcelona and all of its management deserve to be grateful for the achievements brought about by Xavi's presence as the main coach. Xavi has built the quality and confidence in his players to play at their best since he was brought in, he has taken Barcelona to a different level compared to previous coaches.
Last season Xavi and his team managed to win two domestic titles, but unfortunately they were still too weak in the Champions League. Barcelona must improve and continue to try their best in the Champions League, but to be honest it definitely takes extra time and effort.
Barcelona advances in every round except the UEFA Champions League, which is their subsequent priority. Xavi Hernandez is the best thing that has happened to the blaugrana in recent years. The club was an utter shambles left by Ronald Koeman, who brought streak losses to the team, and they had no single hope of survival, instead pushing and battling to win a game. That didn't happen until the president, Joan Laporta, fired him and named Xavi Hernandez as a prospective replacement. Since then, everything at Camp Nou has improved.
