Terrible comparison. Van Dijk is three centimetres taller.
I agree with Quincy's take, anyway. A striker who can appear to be in an imperfect position to score, and then impose himself on the defence at the same time as moving faster, and finish emphatically, and do all of the above often ... gotta say at the fee and wages we're being asked I'd be stoked to see him in our colours. It's a lot but it's sounding like value for money.
