De ligt is probably the best example of how the mental side of the game should always be valued over the physical. Because De Ligt is the ideal centerback physically, like I can’t come up with one flaw. But mentally he’s average. So many clumsy mistakes, just doesn’t read the game very well. And I don’t think it’s something that can really be taught, so his age doesn’t matter too much, he’ll be that same clumsy guy at 30.
