Everton majority shareholder Farhad Moshiri has moved to reassure supporters about Romelu Lukaku's future at the club.
Speculation that Lukaku will leave Goodison Park has reached a new level after he told Everton he does not want to sign the new contract on offer.
But the Merseysiders remain determined to tie their star striker to an extended deal, which would make him the club's first £100,000-plus-a-week player.
Moshiri told talkSPORT: "It's not an issue. The club is confident with the strong relationship it has with the player and the agent.
"He has over two years left on his contract and the new, improved contract is recognition of what he's done for the club. No one should worry -- he is our player."
Last week, Lukaku's agent Mino Raiola claimed the deal was "99.99999999 percent agreed," but the 23-year-old Belgium international appears to have had a change of heart.
At the weekend a Belgian broadcaster asked Lukaku whether he was going to sign the contract, whether he was still reflecting on it and whether there was an agreement and to each question the striker answered: "No."
Suggestions then began to emerge that there was a disagreement over a proposed release clause, with Everton wanting it set at £90million -- which would require any club to break the world record transfer fee -- and Lukaku's side looking for the figure to be closer to £70million.
Press Association Sport reported that further developments had seen the player inform the club after training on Tuesday that the new contract would remain unsigned.
Lukaku, the Premier League's joint top scorer with Harry Kane on 19 goals, has regularly spoken about his desire to play in the Champions League.
Everton have been the best of the rest behind the big six under manager Ronald Koeman this season but remain eight points adrift of fourth-placed Liverpool.
Former Everton captain Phil Neville said he felt the club must do everything they can to hang on to Lukaku.
Neville told BBC Radio Five Live: "If Ronald Koeman's building a side that's willing to challenge for a Champions League place, he has to keep hold of Romelu Lukaku because to replace him Everton will have to spend £40-50m."
