Romelu Lukaku has left Chelsea to return to Serie A on another season-long loan deal, this time with Roma, and it means he remains one of the Premier League's great enigmas.
The Belgium striker's 121 goals puts him 20th on the list of top scorers in the Premier League's 31-year history, just shy of Dwight Yorke and Nicolas Anelka but above Cristiano Ronaldo and Didier Drogba.
Lukaku's latest Stamford Bridge departure comes 12 years after he first joined the Blues from Anderlecht as an 18-year-old, and it follows two summers on from him becoming Chelsea's then-record signing for £97.
