Not arguing for the sake of being a dick. But that's my point.
It's all well and good mentioning those players, but the 17 other defences Torres faced were arguably weaker than the defences Kane is playing against. There are more competitive teams this year than there were in 2007-2008.
No real issue if you take Torres to be the better player though. He was top drawer when he landed in Liverpool, was so jealous he wasn't a United player.
I don't see having an objective discussion as either party being dickish. Kane's a hot topic, so he's going to be held to the scrutiny of strikers at the higher end of the game.
As for your points, there's just no way they're true. The PL as a whole was atrocious last season and that was verified by the performances of its top sides in Europe. The level is better this season than last, but still nothing to write home about.
Torres joined Liverpool in 2007, the same season United won the CL. They [United] lost 5 times (City*2, Bolton, West Ham and Chelsea) and drew 6 (Reading, Portsmouth, Arsenal, Spurs, Middlesbrough and Blackburn). That means four losses to teams outside the top 4 and five draws. These were teams going up against the strongest United side of the 00's.
Lescott, Jagielka, Laursen, Mellberg, Samba, Ooijer, Campbell, Dunne, Corluka, Neill, Gabbidon, King ('08 season), Woodgate are centre-backs, outside of the top 4, that Torres faced. They were strong players in 2007 and better than what we have out there now in equivalent placed teams barring the outlier that is United. Even then, Melllberg and King would give anyone we've got now a run for their money as starters. Fodder at the bottom end hasn't changed much, if at all.
Whether you add the best CB's in the world at that time to the mix or not, Torres faced tougher defenders than Kane.
This notion that the league is collectively better than it was because 'future' or 'money' seems reasonable because the top teams have gotten worse, not because the lesser teams have gotten better. The standard drops and a new 'top level' is accepted. This isn't a dig at Kane, btw, because it's the same across the board. The standard for excellence has dropped and nobody expects the PL sides to do anything in the CL these days so it's put to the side and the focus becomes almost solely about the PL, which leads to a false impression of the strength and quality of the competition.
