England boss Roy Hodgson knows he's selecting a squad from an ever shrinking talent pool.
Hodgson drafted in Tottenham midfielder Jake Livermore - who made his England debut against Italy last month - and uncapped duo Adam Lallana (Southampton) and Raheem Sterling (Liverpool).
The England boss is aware the percentage of players available for him is unlikely to improve.
He said: "We can't deny that. Would I prefer to have a reverse of that statistic, with 68% of players being English? Of course I would.
"But that's not going to happen. The Premier League is fantastic. But it embraces all the top European players.
"One of the other facts we can't deny is the top clubs know where the best talent is, and often go out and buy it.
"That top talent, at a young age, finds it difficult to break into the team because of the established European talent in front of them."
