#3 Lack of experience
If there's one thing we've learned from Barcelona over the last few seasons, it is that the team is regressing. In that regard, hiring a coach without a significant track record appears to be a huge gamble.
Xavi will likely bring an exciting style to Camp Nou, but he doesn't have the experience to rely on. Even though he has done a commendable job with Al-Sadd in Qatar, it is important to note that there's a huge chasm in level between the Qatari league and La Liga.
The fact that Barcelona are in a terrible situation at the moment only complicates matters. Xavi will be under pressure to turn the club's fortunes around. Without experience, can he be trusted to lead Barcelona's rejuvenation?
#2 Not enough quality players in the Barcelona ranks
Should Xavi emerge as the next Barcelona manager, it is quite certain the Blaugrana will return to their possession-based style of play. The Spaniard was a master of the art during his active days as a player.
However, there's a huge question mark on whether Barcelona have the required personnel to adopt such a style of play at the moment. Veterans such as Sergio Busquets, Gerard Pique and Jordi Alba are already past their peak. They've lost their sharpness and ability to press like they used to.
The likes of Memphis Depay, Martin Braithwaite, Luuk de Jong and Ousmane Dembele are not well-suited to the Blaugrana's style of play. Ansu Fati, Riqui Puig, Pedri and Alex Balde have shown promising signs, but are too young to be entrusted with the burden of carrying a team in decline.
Moreover, Xavi would need some time to inject his philosophy into the team. Unfortunately, there seems to be no time for that, as Barcelona need to produce an instant turnaround after their poor start to the campaign.
The Blaugrana currently rank ninth in La Liga, having won just four of their ten games in the Spanish top flight this season. They also stand the risk of failing to qualify for the knockout stage of the Champions League, with just one victory in three games this season.
#1 Poor structure
The structure at Barcelona right now isn't the best. The club has gone through a lot of changes over the last few years, starting from the sporting area to the executive section.
Xavi would have very little say regarding who he gets to work with at Camp Nou, at least for his first few months in charge of the club. It would make more sense to hire someone from within the club right now as a temporary option.
Ronald Koeman's assistant manager Alfred Schreuder did a great job in the 3-0 triumph over Levante last month. Garcia Pimienta was impressive during his spell with the youth team, and Sergi Barjaun has also proven to be a decent option.
It wouldn't be a bad idea to give a chance to any of these names on a short-term basis before bringing in other personnel.
