Former Tottenham captain Ledley King insists England fans have plenty to look forward to.
King, 33, believes there is a new generation of potential stars emerging with the likes of John Stones and Calum Chambers already in the squad and others like Eric Dier waiting in the wings.
"There's no reason why in two or three years' time we couldn't see a generation of defenders every bit as good as mine," King told the Daily Star.
"I think in my time we were fortunate to have some top class defenders.
"It was probably one of England's strongest positions. We had a number of good players there.
"But things change. At the moment we are an exciting team going forward. We have good young players in forward positions.
"But there are good young players that can in the future hopefully be top players. Players like Chris Smalling and Phil Jones at Manchester United. I expect them to improve under Louis Van Gaal.
"Stones at Everton, Calum Chambers, Steven Caulker. I'm going to keep an eye out for Eric Dier as well.
"These are players who've got big futures and hopefully can be the commanding centre backs that you need in a national team.
"It can take a year or two for people to cement their place. But Cahill looks like a top centre half who can play for England for the next few years.
"It's up to the rest of the players to push for spots in the team as well. Young players need time and the experience of playing in the team."
