6. Nathaniel Clyne (Southampton)
Another Southampton youngster – this time poached from Crystal Palace – Clyne has been a regular at the back for leaky Saints despite his tender years. The 21-year-old boasts over 120 appearances for Palace, making him vastly experienced already, and he has impressed in the Premier League with his surging runs from right-back. With Kyle Walker struggling for form and Glen Johnson unconvincing, there could be room for Clyne to sneak in the back door for England.
5. Andre Wisdom (Liverpool)
Another full-back knocking on England’s door is Liverpool’s Wisdom. Few people outside Anfield had heard of the 19-year-old before this season but he has forced his way into Liverpool’s first team under Brendan Rodgers and never looked back. Wisdom, who has been capped at every youth level by England, looks solid defensively and is good in the air, leading the suggestions that he could play at centre-back in the future.
