What's laughable about that? Lukaku, while being rank in the last fourth of the season, still got 18 goals in the league, which is nothing to be scoffed at in the PL. He won't match what Zlatan has done this year, few strikers would, but if they sign Lukaku I'd put good money on him getting 25 league goals next season. He's still only 23 as well, either he could be there for a long time or they'd get good money if they were to sell him on as well. Would be a very good purchase for PSG, only negative would be his lack of European experience.
