Lukaku isn't the answer for Chelsea, not now, not next season or the next season or 2 after that IMO. There's no doubting his goalscoring ability, strength and movement, it's his hold up play and touch at times that lets him down.
And with him only being 20, all that wont come good till later on in his career and with games, and he wont get that at Chelsea cos they want ready made, proven strikers!.
So what does he and Chelsea do, just keep loaning him out to get games and fine tune his game?. I cant see that tbh. I don't think he'd accept that.
I think if Chelsea sign a couple of top strikers for next season, Lukaku will ask to leave and could we afford him?. Doubt it, not even IF we qualified for CL IMO!. I think they'd want there money back or slightly more and can we afford to spend that on one player, even if we had the added riches of CL money?. I don't think so unfortunately!.
