No but him having significantly less games against the poor sides compared to Moore playing a full season against them will obviously impact on their performance across the whole season.
Let's look at it another way. Moore played in the 8th best team in the league last year so would've played for the stronger team in most games, bagged over 20 goals. Mir played in the 18th best side in his league, almost always on the weaker side but still got into double figures, despite your claim that he may as well not have bothered in at least those 8 games against the CL sides. Take a look at the bottom 5 from the Championship last year, only one team had their top scorer get to double figures.
So even sticking with your farcical notion that La Liga is in some way comparable to Championship, please kids stop laughing at the back, Mir out performed his peers in a comparable situation. I've not watched him in 6-7 full games though so what do I know?
