Forgive me my Spanish isn't the best what does that mean?
Well that was a generation of Real Madrid players ( the class of....quinta) coming from their academy that got to the first team in the mid eighties of which the most famous representative was Butragueno. He was nickenamed El Buitre, (the vulture) and the rest were Michel, recently sacked as Sevilla manager, Sanchis, Martin Vazquez and Pardeza.
They all were players of great technical ability but lacking a bit in fighting spirit.
So the translation would be something like " the class of the vulture" ?
