Former Manchester United striker Ruud van Nistelrooy has revealed how he used to study the games of his old Arsenal rival Thierry Henry in order to improve - but was once prevented from challenging the Frenchman for the Premier League Golden Boot by Sir Alex Ferguson.
Van Nistelrooy and Henry are two of the most dangerous attacking players in modern English top-flight history, and they were both at the peak of their powers when representing their respective clubs between 2001 and 2006.
The rivalry was built on respect, however, Van Nistelrooy insists, and he says he was often left in awe by Henry's ability.
