Southampton full-back "?Nathaniel Clyne has admitted that England's defence needs to improve, "?Mirror Sport reports.
With the European Championships just over two weeks away, the Three Lions are struggling to settle at the back and they have failed to keep a single clean sheet in their last four matches.
During their recent friendlies against Turkey and Australia, they conceded some sloppy goals and Clyne recognises that it's a major weakness.
"We analyse the games and see what we can do better" the Liverpool full-back told reporters.
"We can definitely do better defensively. It shows us our weaknesses. We're just about learning from them."
Clyne faces a tough task ousting Kyle Walker from the starting XI but he relishes the competition.
The 25-year-old added "There are players fighting for positions all over the field - everyone has to play well when they get the opportunity to show the manager what they can do. It's healthy.
"It's good - it keeps everyone on their toes and everyone fighting for positions. Everyone wants to be hungry with the determination to get themselves into the squad."
Roy Hodgson is set to reveal his 23-man squad on Tuesday before England tackle Portugal two days later in their final warm-up game.
Clyne should comfortably secure a place on the plane to France but the likes of Daniel Sturridge, Danny Drinkwater and Andros Townsend may be fearing the axe.
