Alcaraz is out of Monte Carlo due to injures. Nadal should have had a limited career due to his extremely physical game. He overcame it.
Alcaraz has a similar challenge. He needs to learn from Nadal, if possible. If this pattern continues, he won't fulfill his ambitions and the predictions by some that he'll surpass the Big three.
He could be out of tennis in five years if injuries pile up. Ask Del Potro.
