I don’t generally disagree with much of that other than:
The fact PL teams generally outperform BL teams, bar the top 2 teams, aside from the few instances you mentioned.
Hernandez/Kalou were 2 of the most prolific scorers last season. Kalou is past it to.
Kagawa was a star before leaving and yes Xhaka is being shown up a tad more here.
We can all agree Draxler isn’t a top performer in BL and wouldn’t initally be a top performer in the PL. He’s a project no 2 ways about it even if RonnieC thinks he’s world class because he starts for Germany.
I’m not saying the top players i nthe BL aren’t going to perform here. KDB and Mkkhi are class, Reus, Auba and Muller. Draxler might perform better in a better team, but he’d probably just be another Nasri type of player. Immense talent, a good player you’d happily have in your team but never fulfilling his potential and being a bit mentally weak into the mix.
