The most painful aspect to me is that it seems his sole attacking move is to twat it vaguely in the direction of the goal regardless of the position of his teammates (or whether anyone is actually in the box in the first place). It's just so braindead and lazy. Players like Walker take a lot of shit for being nothing but speed merchants/athletes but more often than not they actually have the ability to find a man in the box, and Clyne in comparison seems genuinely incapable a lot of the time. His technique is fine (if unspectacular) - is it an intelligence thing?
Something definitely has to give with him and Milner. I know people think they are the least of our problems but I'm not sure I agree - they are a problem for us when it comes to taking on sides looking to sit deep and frustrate. We don't need them to be skinning players for fun and racking up assists, but they need to be more threatening on the ball because right now they are predictable to the point of uselessness in attack, and they are all too often absent in defence. The opposition gameplan can afford to mostly ignore them, meaning they can double up and crowd out our better players who play more centrally, who then have zero room or space to create anything. It's a knock on effect that detracts from the overall team.
I'm not saying he's not a good player, and I'd 100% keep him in the squad - he's the type of steady, reliable player you need around to win things. But I think we need significantly more in both FB positions if we genuinely want to break this annoying habit of looking horribly blunt against the shit teams. It's not the only factor, but it is a decent sized one.
