Yamal makes a piss poor Barca from last season into the best team this season, destroying both Bayern and Real back to back. Way more impressive than battle for a top 4 in EPL (something Aston Villa can do).Palmer is carrying a piss poor Chelsea side and has the most G/A in the world since the start of last season in the toughest league in the world.
Yamal is playing against a dysfunctional Madrid side which is widely being mocked by Barca fans and got spanked at home by a side 7th in Serie A.
Palmer is facing tougher opponents consistently while playing for a much weaker team, putting up way better numbers while passing the eye test with flying colours too. Palmer is doing creative and unique things with the ball week in week out.
The lack of objectivity on this forum is hilarious.
Yamal is doing exactly what you described about Palmer. And shine way more in big games than Palmer.
