It took Romelu Lukaku just 15 minutes to score on his second Chelsea debut at Arsenal in August.
It was a sunny day, Chelsea were imperious and their returning centre forward looked to be the perfect fit. Finally, the champions of Europe appeared to have a natural No 9.
Less than four months on, Chelsea still have one and we can expect him to be involved against Tottenham in the Carabao Cup on Wednesday.
But over the course of half an English season, Lukaku's faith in his ability to succeed in his second spell at Stamford Bridge appears to have waned.
