5. Ruud van Nistelrooy
When Manchester United spent a massive £19million for PSV Eindhoven striker Ruud van Nistelrooy back in 2001, fans were extremely critical of their manager buying a rather unproven striker for such a high fee.
But it proved to be a stroke of genius, as Van Nistelrooy bagged 23 goals (only losing out to Thierry Henry’s 24) in his first season, as well as scoring 10 in the UEFA Champions League. He finished the season as the PFA Player of the Year, and has gone on to become Manchester United’s record leading European scorer with 38 goals.
He became a legend at Old Trafford – like many others – before Real Madrid swooped in for the Dutch striker.
