Chelsea are set to offer Romelu Lukaku an extension to his current contract, including an option to return to Everton on loan next season.

The Belgium international, who has spent the season on loan at Everton scoring 15 goals in all competitions, has been a revelation for Roberto Martinez's side this term.

Reports previously suggested Lukaku had fallen out of favour with Blue boss Jose Mourinho, who is likely to sign Atletico Madrid striker Diego Costa imminently - increasing the competition for places in Chelsea's attack./

According to The Independent, the west London side are ready to offer Lukaku a new contract which would include a loan option for the striker to go back to the Goodison Park next season – and if Lukaku became available, The Toffees would be willing to pay £20m to secure his services.

The deal would be perfect for Martinez - who has reportedly expressed his desire to bring the 21-year-old back to Everton - as he needs to strengthen the squad ahead of next season given Gerard Deulofeu's expected return to Barcelona.

This comes after Lukaku's agent Christope Henrotay revealed last week that they are waiting to hear Mourinho's plans for next season, admitting that the expected arrival of a big-name striker at Stamford Bridge may affect his client's future.

The Portuguese boss has admitted several times this season that he is desperate to sign an established centre forward this summer, with Fernando Torres, Samuel Eto'o and Demba Ba all failing to impress this season.
