Joaquín Sánchez means in slang: Although he is the youngest player in football, he may be the oldest. Joaquin, an almost forty-year old man, has the ability to move at a teenage pace despite his 21 professional seasons. He is someone too old for what he does, but he keeps doing it. And, perhaps, there is a deal with the Devil to preserve his skills despite his age. This can be used as a description of someone who is too old for something, but still does it well.
