Manchester United captain Gary Neville admits the reliance of Premiership clubs on foreign talent has hurt England's international prospects.
Neville, one of the few homegrown players to enjoy consistent success at home and in Europe in recent years, also accepts that English clubs' reliance on foreign-born talent has been a problem for the national side.
He told The Times: "We have to question how good we truly are.
"Better than we performed in this World Cup, for sure, but have we overestimated our strengths on the basis of our strong record in the Champions League? Possibly.
"The success of Manchester United and Chelsea cannot be a reliable guide to the merits of the England team, given the number of top-class players from overseas."
