There have been rumors of a major striker signing for 2 years. Those turned into Ba and then Eto'o. Chelsea is very unlikely to let Lukaku go anywhere. They value young talent and have no need for the money he'd bring. Lukaku also happens to be good friends with Hazard whom Chelsea want ot keep away from PSG. Jose wants to humble Lukaku but he doesn't want to sale him. After the World Cup as teams form for next season Lukaku will be back in the fold. It is very unlikely he doesn't earn at least second striker status at that point given his rare combination of size/skill.
