Romelu Lukaku returns to Stamford Bridge tomorrow afternoon, with the chance to emphatically remind his former club of his quality.
More than two years since Jose Mourinho allowed Lukaku to move to Everton, initially on a loan, the Belgian has begun to fulfill his enormous potential and will return to Chelsea, as the league's top scorer.
Mourinho has of course been sacked, taking away an element of edge to this occasion, however, the opportunity remains for Lukaku, to prove to his previous employers that they were wrong to let him go.

Why did Chelsea sell him?
At just 22, and with 57 Premier League goals already to his name, Chelsea's decision to let Lukaku seems odder by the month.
Hindsight is a wonderful thing and considering Diego Costa's poor form this year - the Spaniard has scored just six league goals, compared to Lukaku's 15 - many Chelsea fans would welcome back the Belgian.
Back in 2013, as he prepared to embark upon his first season back in the Chelsea dugout, Mourinho deemed Lukaku surplus to requirements, with Everton initially taking him on loan followed by a club record transfer fee of £28 million the following summer.
Should Everton look to sell Lukaku they would undoubtedly make a significant profit on that fee with the striker likely to improve even further as he gains experience.
Mourinho has always favoured a small squad of players, whom he can rely upon completely and raised questions over Lukaku's attitude in the summer of 2014.
Chelsea's former manager stated to SkySports "he (Lukaku) was not highly motivated to come to a competitive situation at Chelsea.He wanted to play for Chelsea but he wanted to be clearly the first choice striker, which in a club of our dimension, it is very difficult to promise to a player."
Though at 21 Lukaku could have been more patient, his ambition in the modern era is admirable and Chelsea chose to sell on their signing from Anderlecht, in order to fund their moves for Costa and Cesc Fabregas.
Will he stay at Everton?
Despite possessing some of the most exciting young talents in English football and being a draw away from the Capital One Cup final, Everton have underachieved so far this season.
Roberto Martinez's side have thrilled going forward with Ross Barkley a stand-out performer, however, they have only won six of their 21 league games and are currently sitting in 11th.
Champions League qualification looks increasingly unlikely for the Toffees this season - they are eight points behind Tottenham in fourth - and Lukaku may begin to look elsewhere as a result.
Lukaku's agent Mino Raiola has publically stated that “if we had met each other earlier, he wouldn’t have played for Everton”. As a man who also advises Zlatan Ibrahimovic and Paul Pogba, Raiola is a very well connected figure across European football and will be fully aware that his client would not be short of suitors.
Manchester United and Paris St Germain are just two of the clubs to have reportedly expressed their interest and Everton fans may have to get used to life without their star striker next season.
