Mallorca youngster Luka Romero became the youngest player ever to feature in La Liga when he came on against Real Madrid on Wednesday.
The 15-year-old replaced Idrissu Baba in the 83rd minute of the 2-0 defeat to Zinedine Zidane's side to set a new record in the Spanish league.
The previous record had been set over 80 years ago when former defender Sanson made his debut for Celta in December 1939.
The attacking midfielder had been included in the Mallorca matchday squad for clashes against Villarreal and Leganes in recent weeks, but was finally given his first taste of senior football with a brief appearance against the capital club.
