Arnaldo Castillo is a Paraguayan striker bringing a potent mix of physicality and finishing ability to O'Higgins in Chile. At 28 years old and standing 186 cm tall, Castillo is a classic center-forward who thrives on service into the box. His powerful frame allows him to hold off defenders, while his movement and clinical touch make him a constant goal threat. His career path from Paraguay to Chile is a common one for South American talents, and he has adapted well, becoming a key offensive weapon for his club. Castillo's style is direct and effective; he is a penalty-box predator whose primary objective is to put the ball in the net. For O'Higgins, he is the focal point of the attack, a player whose goal-scoring form is often the difference between victory and defeat.
