Roy Hodgson's selection of Arsenal's Calum Chambers over Nathaniel Clyne is both England's recent games appears a baffling selection.
Chambers has made an encouraging start to life as an Arsenal player, but Clyne was the obvious selection for the right-back berth and Hodgson's failure to utilise the Southampton man is nothing short of staggering.
Clyne has been the most in-form player in his position in the Premier League over the opening weeks of the campaign, and Chambers's inclusion ahead of him is simply not justified.
The 19-year-old has the talent to be an England regular for some-time, but his future is unlikely to be at right-back.
Chambers had admitted that he prefers playing in the centre of defence, whilst Arsene Wenger commented that he sees him becoming a central-midfielder in the future.
Clyne, however, is an out-and-out right-back and could have offered Hodgson a solution to a problem which has plagued the team for some time.
With Glen Johnson often exposed at the top level of international football and Kyle Walker currently out injured, there was a big opportunity for Hodgson to test a new right-back out, but he failed to try that.
Clyne could have been given a gentle introduction against Estonia and San Marino, but instead Hodgson still does not know how he will perform on the international stage.
At 23, the Saints full-back has a glistening future, but he has missed a big chance to make his Three Lions debut.
Chambers struggled in both matches, despite the low-class of opposition, and it is hard to see exactly what Hodgson gleaned from his inclusion in both games.
It is yet another error from a manager who is coming under constant criticism, despite England's winning form in qualification, and it could be a costly mistake in the future.
