Lukaku? Well, Anderlecht refused an offer from Chelsea this year, so i think the chance to get him might not be that big.
That's not entirely true.
2 years ago (kid was 14 at the time) Chelsea approached him & his parents offering him 1 million € to move to England and play in the Chelsea youth teams. Anderlecht convinced Lukaku & his parents to stay in Belgium by pretty much guaranteeing him some playing time. This playing time ended up coming sooner than expected.
I happened to see an interview last night with an Anderlecht director and he was pretty open about the whole situation: "Every big club is following Lukaku and we will not be able to keep him in the long run. However, we would like for him to stay untill he is about 19 years old."
Also read an interview with Lukaku himself a few weeks ago, and despite the fact that he is still a kid, he seems to be pretty grounded. I get the idea that his entourage, as well as Anderlecht, know perfectly well what they're doing. Something that's not always the case with young, hyped up talents.
Right now, I don't think any team can buy him outright. The only possibility to me seems buying him & immediately loaning (uh oh) him back to Anderlecht for 2 - 3 seasons.
