I wouldnt say snuffed out, but Thiago was the least impressive of the spanish midfield trio. Martinez ran things, while Ander Herrerra impressed quite a bit too (and no, not with the handball goal). Snuffed out would be erronous, because what they snuffed out wasnt spanish midfield, which was the reason they dominated the game possession wise for 85 mins (England got excited or got into the game only at the last 5 mins). The reason they didnt go anywhere (besides settling in too much at 1-0) is as usual in these levels, or the backside of spanish footie school, they dont really have clinical edge to their attack, no real presence there. Alot of passing going nowhere with no teeth upfront.
But the domination of the play was quite obvious. How they were constantly available and open for passes with deft touches were quite a contrast, to England's version of a player looking up and having no one open to pass to, no one moving/making themselves available. It was mainly the fullbacks who had this predicament, they started things, had to run forward solo, or make random risky pass. Or give it to CB/DM who hoofed it up (poor Wellbeck and Sturridge, no real service). Which is allways the same issues with England, youth team or otherwise. So both teams flaws/football school was as obvious as usual.
But standout wise, Kyle Walker, super impressive RB. Look forward to seeing him in Spurs next season. Him and Smalling where best english players.
