Why are you mentioning Dier when he hasn't played a single competitive minute, and isn't even on the bench?
Sure he is here because things weren't going well. That's neither here nor there when it comes to assessing who is up to it in his view. He can only make that judgement on what he sees, under his way of playing.
I guess I'm just surprised that lots of people seem so surprised. We've been told over and over that a) there will be plenty of bumps along the way. This won't be the last. and b) That Ange insists that he and no one else assesses the players suitability for the squad and he does it his way whether we, Levy, or pundits like it or not.
Down to interpretation of what 'bumps along the way' is as differs for people and being out in the first stage of the cup is not one of them for me!
I guess those that are surprised might be more ambitious than others too and that we could have had a chance at the cup.
