Pierre-Emerick Aubameyang was given the perfect example to hone his craft when starting out at AC Milan alongside Ronaldo - though he admitted the Brazilian legend was "a bit fat by then".
The original R9 spread terror throughout defences across Europe and on the international stage, earning him the nickname Il Fenomeno (phenomenon), having fired Brazil to their World Cup triumph in 2002 - his second winners medal - as well as developing his reputation as one of the greatest striker's in history at Real Madrid, as well as spells at PSV, Barcelona and Inter Milan.
However, injuries, weight issues and age had taken their toll on the three-time FIFA World Player of the Year by the time he pitched up at San Siro aged 30. Madrid agreed to sell Ronaldo to Milan for a cut-price €8million fee in January 2007, though his powers were significantly on the wane.
