Xavi was a good player, but he didn't manage to make the transition to a great coach, as was evident in his time at the helm of Barcelona and Spain. While one might think that the squad is facing a shortage of manpower, or that Xavi is inexperienced enough to command a first-team team, it may be necessary for someone else to take over in the face of the current poor results.
Xavi will be replaced by current Girona coach Charles Michel, who has managed to lead his team to the top of the table surrounded by formidable opponents. In fact, in September of this year, Xavi has renewed his contract with FC Barcelona until 2025, and the contract also includes an option to renew. However, contract renewals and team standings, and even the control of the dressing room, are completely different issues.
Just in the most recent round of the league, Barcelona lost 2-4 against Girona, and although Girona are currently top of La Liga, perhaps the situation would have been completely different if Barcelona had beaten the new champions at the time.
Girona FC has achieved an excellent record of 13 wins, 2 draws and 1 loss after the new coach Michel took office, accumulating 39 points, surpassing Real Madrid, Barcelona and Atletico Madrid, completely disrupting the three-legged pattern of La Liga, and Barcelona began to contact Michel after losing to Girona, hoping to hire this coach and lead the team back to the top.
Of course, before Michelle's arrival, if Xavi is unfortunately sacked by Barcelona, second team coach Marques will take over the team temporarily until the club officially signs Michel.
