Pep doesn't 'usually' do that though does he, he hasn't 'created' that before as such. At both Barcelona and Bayern, that was already the case. He bought as many foreign players as he did native ones at both, at at Bayern I dare guess more.
For me if he was looking to do that, probably would have done it 4 or 5 years ago. There may be something in futureproofing against changing quotas but generally I think he is going for the players he happens to think are best fit, and proven in the league. Rather than because they are natives.
Agree with all the rest entirely.
