Spain manager Vicente del Bosque says the "English" style of football no longer exists because of the number of foreign players in the Premier League.
In an interview with the Guardian, Del Bosque said playing regularly with foreigners has even influenced the style of England and other national teams.
"There is no 'English' football any more, I don't think: no authentic English style," Del Bosque said. "Because of the mix of different styles, the arrival of players from abroad makes it impossible to maintain an 'English football.'
"I imagine there are still some idiosyncrasies at English clubs, teams that are very English, but on the pitch it's difficult to guess where teams are from.
"The purity of each [national] style has been lost. I don't think there's much difference between any countries. Maybe I'm missing something but even with the national side England has started to look like other sides on the continent."
Among the current foreigners in England are seven players of Del Bosque's latest Spain squad, including four from Chelsea -- Pedro, Diego Costa, Cesc Fabregas and Cesar Azpilicueta.
"It's been good for us that players went abroad to play, without doubt; that's one of the most important factors," Del Bosque said. "It opened our minds, a major advance, I have no doubt about that. When you have Cesc Fabregas aged 19 and he's Arsenal captain, that's good for us.
"That said, sometimes I complain that I would like to base the squad on one or two clubs and [our players] are more dispersed now: some at Arsenal, Manchester City, United, Chelsea ... Nearly all the countries who've won international tournaments have done so basing themselves on one particular club side, be that Bayern Munich or Juventus or whoever...
"A block is useful but now it's more dispersed. That said, we've got four from Chelsea: Costa, Cesc, Azpilicueta, Pedro. You can take things from that. We have very few days, so it makes sense. It's not that you copy what players do at club level, it's that you would be stupid not to."
Del Bosque added that diversity within leagues is not limited to England.
"It's a problem [in Spain] too," he said. "The other day in the Atletico starting XI, there were two [Spaniards]; Madrid played with just three ... There are many foreign players but I shouldn't complain too much because it's the clubs' policy and they decide, not me."
Del Bosque also said the Spanish style is more than just "tiki-taka," calling that term "a simplification."
"If you had to put a label on Spain you wouldn't call us defensive, if you say tiki-taka it implies having the ball, playing attacking football, but we've been very defensive too," Del Bosque said.
"We've been champions scoring very few and conceding very few and we're still in that dynamic. People don't call us defensive, and yet..."
The 64-year-old credited a strong infrastructure for Spain's recent international successes.
"We've done things the right way: there's a good structure, an increase in elite facilities, a very good coaching setup, even the [footballing] culture of the general public has improved," he said.
