(CNN) -- Real Madrid and Barcelona both comfortably won on Saturday, but for once Spain's two most dominant football clubs were overshadowed by a third-tier team which has been saved from extinction after receiving a huge injection of cash from the world's richest man, Carlos Slim.
Just over a decade ago Real Oviedo played in La Liga alongside Real and Barca, but mismanagement from the club's directors took the Asturian team to the brink of bankruptcy in recent years.
Needing to raise €1.9 million ($2.4 million) by November 17 or go bust, Oviedo's current board announced a share issue earlier this month to attract investment.
Remarkably the scheme took off as fans from all over the world bought the €11 ($13) shares after Oviedo's precarious position was highlighted on the social media website Twitter thanks to the efforts of Spanish football expert and long-time Oviedo supporter Sid Lowe.
Over the past two weeks those fans have bought more than $1.9 million in new shares in the club, and Slim was so impressed -- he described the gesture as "extraordinary" -- that the Mexican tycoon has now pumped in a further $2.5 million to become Oviedo's majority shareholder.
"This challenge and ambition is strictly a sports investment and one that looks to benefit the club and its fans,'' said an Oviedo statement regarding Slim's intervention.
"(The investment) will try to support Oviedo's players so they can reach their goals and the club can reach the division that corresponds to its history and values.''
In September Slim bought 30% stakes in two Mexican football teams, Pachuca and Leon, and he plans to use Oviedo "to create synergies and exchanges between Spanish, Mexican and Latin American football.''
According to Forbes magazine, Slim is the world's richest person with a net worth of $69 billion, having made his fortune in the telecommunications industry.
His widespread interests include providing financial backing for Mexican Formula One driver Sergio Perez.
"Naturally, I have reservations, doubts & concerns," tweeted Lowe on Saturday. "But with c. €2m of shares bought by 13,000+ ppl round world & Slim buying €2m Oviedo safe."
"€1.93m raised by small shareholders alone," added Lowe. "They're the real heroes."
