What I don't get with him, and with any full-back with pace, is why they don't just keep going when faced with open space at the edge of the box.
It's not like there's any tactical advantage to their usual routine of checking back, standing still for a few seconds and then passing it to the player behind them. You keep possession, sure, but there are players making runs in the box waiting for a ball in.
Walker used to do that a lot too, but then, in 2016/2017, he did it a lot less. Suddenly he was bursting beyond the last man in the box, looking to deliver cut-backs or crosses to the far-post. It's probably a big reason why he was so effective towards the end of his Spurs career - he unlearned that habit of stopping and passing back when faced with open space beyond the full-back covering him.
It's not just Aurier - it's Bellerin, it's Clyne, it's quite a few players from other teams that I've heard the same complaints about.
And Trippier I can forgive, because he hasn't got the pace or physicality to beat his man - plus, he delivers great crosses from deep anyway, so he doesn't need to get beyond the last man to pose a threat.
Aurier has the tools to be better than Walker ever was. He's got the same pace, and the same physicality, but he's also got a brilliant cross on him, which Walker never had - his technique was always his weak point. He's also got the same flaws Walker had (a tendency to switch off and be rash at times) - however, Walker eventually fixed that and I'm sure Aurier will too.
But I do wish he unlearns this habit of checking back, more often than not. You have the pace, and the technical ability - get into the box, and cut it back for Harry or Alli to finish. Simples.
Sorry, just a minor gripe.
