I must admit at this point I don't know how big the potential of Havertz is or how close he ends up getting to it, but there's just something about him where you feel he could be an absolute monster if he ironed out a few of his flaws. Again, not sure he can or will - and he can still be a great asset for us without doing so - but yeah, there's definitely something about him. Much stronger and physically dominating than he first appears.. seems to be able to go in to 40-60s in the opponents favour yet still come away with the ball. Imagine if he can pair that ability with being abit quicker, more direct, abit more decisive in what he wants to do. Could be lethal.
I also thought he was a couple years older than he actually is too.
