Both nations are poised to contest a mouth-watering World Cup semi-final clash in Sao Paulo on Wednesday, with the Dutch looking to reach the last two for the second time in four years.
Robben has emerged as one of the Oranje's stand-out performers throughout the tournament, scoring three goals, and Milito says that the Albiceleste must restrain the Bayern Munich winger.
"Robben is an impressive player, a devastating one. Netherlands will be difficult. They're a team who spent the last four years doing a great job," he told Goal.com.
"They have already reached the final in previous World Cups, and they're a team who have, in addition to a great coach, great players.
"They can make the difference and win the game at any time."
Wednesday's last-four encounter kicks off at 9pm.
