If you only look at goals scored (and even then he was very underwheming), not overall game. It's true that quality of attackers in this league (actually everywhere) is abismal but current Lewa is not the best in the league if you watch his overall game. Would prefer somebody who maybe scores less but can run, press, open space, can keep ball, can complete a simple pass... Victor could be that if he got the chance but he won't get it.
The biggest issue is his salary and his demands that he plays all minutes and bitches everytime some kid doesn't pass to him. We would all be fine with him on a minimal wage and coming of the bench like Modrić (who even now is 10x the player Lewa is). It's the same thing as CR7 at United or Suarez in his last seasons here.
