Top 3 World Cup stars Chelsea should have never let go

#2 Romelu Lukaku

Lukaku celebrates Belgium's win

The Manchester United striker has been in superb form for the Belgians at the World Cup this year. Having scored 4 times in 4 games he is one of the contenders for the Golden Boot along with Harry Kane. He has ensured that Belgium qualified for the semi-final after a good display up front to dismantle the mighty Brazilians without much fuss.

Now the all-time leading goalscorer in the history of Les Diables Rouges, Romelu Lukaku has won the football world over with his impressive consistency, drive and determination.

He has scored with both feet and his head and is in hot form at the World Cup. He will look to inspire Belgium to an elusive World Cup final if they can overcome France in the semi-final. Chelsea should have held on their player and stuck with him during his developmental phase and nurtured his growth. However, the rest, as they say, is history.
