I am a huge fan of Dahoud. He's so good on the ball and has got a great engine on him, however, as you would expect from any young player, he is inconsistent but he has crazy potential as a box to box creative midfielder. I haven't seen a whole lot of William Carvalho but from the little I've seen, he seemed to be very assured on the ball and could pass it long and short with both feet not to mention that physically he is as good as it gets but then again, he seemed a bit slow and has consistency problems. But both of these players have decent/good defensive skills and are better on the ball than Bakayoko in my opinion.
