Not this season, and I wouldn't trade Mandzo for Benzema for various reasons (performances vs the Cagliaris for us don't matter, big CL games do, and Benzema is scum), but yeah.
Benzema was considered better than Mandzo for most of their careers. Current form doesn't change that.
To each their own, I just find it funny that some only recently discovered what Mandzukic brings to the table (or maybe they didn't but only noticed his goals), and they're the ones overreacting. Mandzo's best for us was in 2nd half of 2016-17 season, following which, they didn't want him in the starting XI for the following season.
