Dier is pretty versatile as a player, actually. He can play some bloody accurate long passes at times, he can occasionally put in great crosses, and he wasn't a bad right-back when he did play there.
But his considerable struggles when playing at center back just confuse me. He's like Toby, but without Toby's excellence at his primary job of being a CB. And while Dier is a *good* defensive midfielder...I still think that, deep down, he's so ideally suited to replacing Toby given his talents that it's a waste to play him at DM.
And yet, the guy just cannot play in a back-line without making a lot of errors and making us look a lot shakier as a result. It's amusing, but also frustrating.
Either way, we're lucky to have him as is - he's a good player, who gets on with his job, hates Chelsea and is basically Dele's hype man. Truly multifunctional chap.
But there's a world-class center back lurking in him somewhere, if only we could find it.
