I don't think this could even be considered his 'breakout' season - hopefully that will be next year! What's impressive is his contribution per 90 in comparison to someone else who's had a good first season in the league, Anthony Martial. Admittedly, Martial has higher totals in the league and even a better per games ratio, but that is by dint of the fact he's been on the pitch over three times longer than young Divock.
The way he's performing, you have to wonder if we actually need to sign another striker in summer, even if Benteke leaves. I've been saying for a while that Lacazette would be a startlingly obvious good move for us (to the point where I'm not actually sure why it hasn't been mooted more already) but I'm beginning to doubt based on the fact that a strike force of Sturridge, Origi, Ings and Firmino (with Goetze behind) is probably more than enough.
