I just disagree. I could give you countless examples of foreign players failing in this country. We play different football but it's certainly not worse IMO.
Of course it's f**king worse. The British blueprint is why we got mullered at the World Cup and played off the park by the first decent team we come across.
Take a player out of a team in Spain and hoy them in a team in England and they'll struggle to adapt (for example Borja Valero), but put a lower English team against a lower Spanish team and they'd get played off the park. They're technically and tactically streets ahead of us.
There's a reason why we've only won 1 out of the last 25 Uefa Cups (or equivalents), our middle to lower teams are so far behind the top echelons.
