The 22-year-old has recently been strongly linked with a £40million January move to French giants Paris Saint-Germain.
Lukaku’s agent, Mino Raiola, has confirmed that the move can go ahead with Everton boss Roberto Martinez’s blessing.
Raiola told Radio Monte Carlo: “Lukaku to PSG? We had a discussion with Martinez, he said he would let him leave Everton if a good offer comes in.
“But talking about the transfer window now makes no sense.”
Lukaku joined Everton in a £28million deal from Chelsea.
