Now that Glen Johnsons tenure as Englands main right-back is no longer safe, similar to the left-back situation with Gibbs and Shaw the nation has some impressive young players vying for the role on the opposite flank: Kyle Walker, Nathaniel Clyne, Jon Flanagan, Carl Jenkinson and Calum Chambers. Ability wise, theyre hard to separate, however Walker is worth singling out because he is quickest runner of the quintet and has a potential to be potent attacking full-back, similar to Daniel Alves at his best. Of course such a pronouncement on Walker could admittedly raise eyebrows due to his defensive issues at times. But in modern day football, how many full-backs combine solid defensive acumen to their tendencies to sojourn forward in attack, with gay abandon, other than Phillip Lahm? You will do well to name ten other such full-backs still alive, but you will find many who can attack competently. Correcting such faults shouldn't be beyond Walker: as previously mention, his pace generally gets him out of trouble defensively and no winger really can outpace him. So once he balances his defensive game, England should have a gem of a right-back in time for Russia.
