Martinez plays primarily a centre-back, though he is capable of playing at left-back and as a defensive-midfielder, having played there at times for Defensa y Justicia and Ajax. He is a ball-playing centre-back and is known for his range of passing and composure on the ball. In the 2021–22 Eredivisie season, he averaged more passes per 90 minutes than any other player. Before signing him, Ajax's scouts characterised Martínez as a left-footed ball-playing defender who is "tough as nails" and possesses winning mentality. At Manchester United, his performances earned him comparisons to legendary former United defender Nemanja Vidić, with Vidic himself praising Martínez for his aggressive defending and leadership. Despite his relatively short stature for a defender, standing at 5'9", he is also effective in duels.
