He had his limitations ofcourse, but at a certain period he was doing great, had an excellent return and was learning to become more than just a poacher, then RVP was signed and it just stopped. If SAF stayed longer, and player Chicha up top with Rooney, I dont know why Hernandez couldnt become a top class striker. Not saying he'd become Aguero, but he was still young for a striker, scoring goals at a big club, and the difference would be confidence. He had all the attributes, was quick, made runs behind the defence, solid header, poacher like instincts, driven, he was a solid finisher with both feet, after RVP, it looked like it all just regressed for him.
