Everton defender Phil Jagielka has said that he believes only Steven Gerrard could be guaranteed his spot in the England team.
The 30-year-old is in the mix for one of the starting centre-back places in Roy Hodgson's team along with players such as Gary Cahill and Phil Jones.
Jagielka told the Daily Mail: "There is tough competition in all positions. It's not just the centre-backs - even the full-backs aren't guaranteed places these days and I look on that as a positive.
"The squad probably don't have as many so-called top-level players as we've had in the past, like David Beckham, so it could be any one of 30 players starting in August and at the World Cup.
"There isn't really anyone nailed down. Possibly Stevie but he's getting that bit older and I see him changing his game for England a bit."
Jagielka has made 16 appearances for England since making his debut in June 2008.
