Chelsea defender Gary Cahill has highlighted the influence of Gary Neville on England's defensive work.
The Manchester United legend is on the backroom staff of the national team.
Cahill said of the former England and Manchester United full-back: "He was a fantastic defender.
"And he likes being hard, and tough to play against, being physical - almost like old-school, whereby you let the attackers know they are in a game and feel your presence, just by being aggressive and getting tight to them.
"It's something we've certainly addressed. We are definitely a lot harder to play against defensively.
"It is about being physical and wanting to win the ball back and putting tackles in - the basics of defending, really. I think at the minute we are doing that really well."
