Arsene Wenger believes England would be a much stronger side if the core of their players were based with only one or two Barclays Premier League clubs.
According to the Arsenal boss, world and European champions Spain have a huge advantage over sides like Roy Hodgson's England because the vast majority of their players either play for Barcelona or Real Madrid.
Manchester United was the club with the most representation in England's disappointing 1-1 draw with Montenegro in a World Cup qualifier on Tuesday night with five players - defender Chris Smalling, midfielders Michael Carrick and Tom Cleverley and strikers Wayne Rooney and Danny Welbeck - in the starting line-up.
However, the remaining players came from three other Premier League sides, Chelsea, Liverpool and Manchester City, and this where Wenger thinks a weakness lies.
"What people forget about Spain, and what they do not talk enough about, is the big advantage of a good national team is when it is based on two (club) teams," Wenger said.
"In the starting line-up of Spain, you have many times seven players from Barcelona, three or four from Real Madrid. The other night (Arsenal left-back Nacho) Monreal was the only player who was not from Barcelona or Real Madrid.
"That is a massive advantage when you go into a game like that, because you can play like a club.
"One of the advantages of Spain is their national team is built on two clubs, if we can have four, five or six (England players) at one club, it will become a massive advantage for England.
"At the moment, all of these players are spread everywhere.
"To look like a good team, you have moments like that where you play well for one half, then suddenly something disappears and you have no team anymore, because the players come from too many clubs."
