Southampton-Watford was probably the worst thing I've sat down to watch since that Open Water movie 15 years ago and that was only yesterday and fresh memories. More than half the EPL games I'm forced to watch are crap. Unfortunately, they're a lot. No tactics, no game plan, mistakes everywhere, just run around usually and hope for the best. There are some teams that try to save themselves from that rather accurate stereotype but that's a small % of the league's full fixtures per year.
And I don't rate the Serie A as high as you think. I just think the EPL is piss poor and without the marketing not many would really bother to call it "the best". More than half the teams are useless and the top teams don't even care about the result some times, just to sell tv rights and tickets. There are like 8 teams that are actually pretty good or better and only 3-4 act like it. That's just how the EPL is.
You praise Harry Kane, a player who struggles to evade defenders who aren't even man marking him most of the time, has around 50% of his goals from PKs and set pieces, creates no goals for himself nor his teammates and remarkably has trouble to tap the ball in some times and has to control the ball within 1 meter off the goal occassionally (check his first two EPL goals from last year, ridiculous first touch). Both Kane and Lukaku NEED space, whilst Icardi CREATES space. Both Kane and Lukaku have 0 to 1.5 player defending them per situation whilst Icardi typically has 3 or 4. And he still has a great conversion rate. Put Kane and Lukaku at Inter during Icardi's era and they're probably gonna have 10 and 25 goals respectively. Over the years. And that's only because Lukaku can score in counter-attacks whilst Kane can't really do that unless he's all alone. And that won't be the case in Italy.
Today Inter had to defend against 10 men and Icardi was hidden between 5 defenders. How many times can Lukaku and Kane say that's happened in their career? I'm also sure as a typical EPL fanboy that's never kicked a ball, you will use "statistics" to "enhance" your "argument". Well, you might notice that Icardi's "chances" and "attempts" are bad when he barely manages to get a touch whereas Kane and Lukaku are more than free to make up their mind before they miss. And that's not coming from me, that's coming from everyone who's played in both leagues in any era and they're quite open about it (Tevez, Torres, Henry, Vialli, Zola, Di Canio, Crespo, Sanchez and so on). There's no space in Italy, there's no midfield and too much space in England. And there's no pressure in England either. That's what they've collectively said over the years.
I'm pretty sure you think that Belotti, Morata and Higuain are worse than Kane and Lukaku. Maybe Luis Suarez was an overrated biter as well.
