Have only seen him when we played them and he was given a hard time by our two at the back. Runs about a lot and obviously a good finisher when he gets the chance.
An elite level striker? Certainly not. Better than what we have? Not sure but certainly a different profile to Havertz.
In addition; he's soon to be 27 so hardly a long term solution (especially for someone that builds his game on running a lot). So it does defer the striker problem for a few years. Unless, of course, they are looking at bringing in two Centre Forwards.
