Chelsea fans have unanimously blamed club record signing Romelu Lukaku for his involvement in Plymouth's first half goal in the FA Cup fourth round tie.
Lukaku, 28, has struggled to keep his promise to the Blues faithful after he went behind people's backs to conduct what turned out to be a damaging interview with Sky Italia.
Since then, the striker has failed to net in important games against Spurs, Man City and Brighton respectively with the sole Chesterfield goal his only rest bite.
