6. Bojan Krkic
- 17 years, 1 month, 22 days
- Barcelona vs Villarreal (2007/08)
The 2007/08 season was a disappointing one for Barcelona. It wasn’t for Bojan, though, who used it to cement his reputation as one of Europe’s young rising stars. The Blaugrana’s miserable 3-1 defeat to Villarreal on Matchday 8 was notable only for Bojan’s first goal in Spain’s top division, following a defence-splitting pass from Lionel Messi.
The local boy featured regularly for four seasons before being offloaded to Roma, but rejoined Barcelona in 2013 after a successful loan spell at AC Milan. But then came the decline amid a crippling struggle with anxiety: Ajax, Stoke, Mainz, Alaves and, finally, a free agent at only 29.
5. Juan Mena
- 17 years, 1 month, 6 days
- Valencia vs Celta Vigo (1941/42)
Mena was the league’s youngest scorer for several decades, after netting the seventh goal in a 7-3 Valencia victory on his debut in December 1941. They went on to claim the La Liga title that season – the first in club history.
