The Dutchman is in awe of the way in which the Mexican is able to remain patient on the bench before taking every chance that comes his way to prove his predatory instincts.
Ruud van Nistelrooy believes Real Madrid striker Javier 'Chicharito' Hernandez to be the model professional.
Since leaving his native Mexico for Europe in 2010, Guadalajara protege Hernandez has found regular first-team soccer difficult to come by, first with Manchester United and now at Madrid.
However, Hernandez has nonetheless maintained not only an impressive strike rate, but also a remarkable sense of professionalism, according to Van Nistelrooy.
