The Belgian striker joined Chelsea in 2011 but has yet to spend any real time playing in the Blues first team, having been shipped out elsewhere.
Now is the time for Jose Mourinho to carve out a spot for the 21-year-old, who could make a real impact next season if he is given playing time.
With the signing of Diego Costa from Atletico Madrid all but confirmed, per beIN Sports' Tancredi Palmeri, the pair could form a lethal partnership and solve Chelsea's recent forward problems.
The player himself is eager to be given the opportunity by Mourinho, per Sky Sports.
"You know, I still have a two-year contract at the biggest club in England, because that's Chelsea," he said. "So I still hope to play there. Chelsea have a good coach."
While Chelsea's frontmen were struggling to find the net last season, Lukaku was banging goals in regularly for Everton as the Toffees racked up 72 points for their best-ever season, per Squawka:
The Blues' strike problems were well-documented: Samuel Eto'o, Fernando Torres and Demba Ba accumulated just 19 Premier League goals between them as Chelsea finished third in the Premier League, per BBC Sport.
Lukaku, on the other hand, bagged 15 goals in 31 games for the Goodison Park outfit, per WhoScored.com. The season before, on loan at West Brom, he scored 17 in 35.
At just shy of a goal every two games, Lukaku is showing remarkable consistency for such a young player. He also has 10 assists over the last two Premier League seasons.
Lukaku is one of the brightest prospects currently playing in the Premier League and is there for Mourinho to utilise as he sees fit.
He decided to loan him out last season; he must not do the same in 2014-15. Lukaku's time at Everton has proven he is a quality player and one who can be relied upon to bag vital goals that Chelsea just couldn't find up front in the most recent campaign.
A Complementary Strike Pairing
While many will claim that the imminent arrival of Costa will solve all of Chelsea's problems, this may not be the case.
The Atletico striker is a great player, but Lukaku offers something different, and the pair could potentially form a devastating partnership.
Lukaku's power and physicality are reminiscent of a young Didier Drogba and are attributes that Costa does not necessarily bring with him.
To have both options available will be key to Chelsea's success next season.
Furthermore, Lukaku continues to show his worth on the world stage as an exciting Belgium team warm ups for this summer's World Cup in Brazil.
He scored a hat-trick against Luxembourg last week and netted another as Belgium beat Sweden 2-0 on Sunday.
Belgium are being touted to go far in this summer's showpiece event, and if Lukaku can keep up his current form in South America, clubs will be queueing up to sign him.
Mourinho must not let him go, and he must make him integral to his plans next season. The Belgian wants to play for the club, and he could prove to be the piece of the jigsaw puzzle that was missing last season.
Even better, he's already on the books at Stamford Bridge, which means there is no astronomical transfer fee required for a player of true quality.
