Barcelona is facing additional financial challenges as a crucial investor has failed to provide the necessary funds to complete an important deal, leaving President Joan Laporta in a precarious position.

Last month, Barcelona reached an agreement with Libero, a football finance company listed in Frankfurt, to acquire a 9.8 percent stake in Barca Vision.

However, according to The Telegraph, Libero has been unable to secure the funds required to finalise the transaction.

This development puts President Laporta in a difficult situation because he personally guaranteed €20 million (£17.2 million or $21.5 million) as part of the arrangement, which played a pivotal role in obtaining La Liga's licence for Barcelona to participate in the current season.

The transaction was part of a series of "palancas" or leveraged deals, that had provided crucial short-term funding in exchange for shares of future income or the sale of club subsidiaries.

Up until now, this strategy had been considered successful, with Barcelona's rejuvenated playing squad performing well on the field and the ongoing redevelopment of Camp Nou.

However, Liberia's failure of Libero to deliver the required funding now jeopardizes a vital component of this strategy.

Barcelona will regroup after the international break and prepare for a challenging schedule of three games in seven days at their temporary home, the Estadi Olímpic Lluis Companys.

In particular, President Laporta and the club's financial team will be eager for a smooth start to Barcelona's Champions League campaign, as they aim to avoid a repeat of two consecutive group-stage exits.
