Personal opinion (for whatever its worth), I've seen KWP several times, don't see it, and in the modern game I think his size is a massive disadvantage.
I don't think it is a coincidence that with our current line up (first 11) we don't get bullied/overrun as much as previous years. We have fairly physically imposing side (Walker, Jan, Toby, Dier, Alli, Dembele, Kane and even Lamela isn't small), really only Rose (who has a very aggressive approach to game) & Erisken who don't fit the bill.
To be a small player in the PL, you have to be top tier exceptional, I don't see that in KWP (but I absolutely could be wrong)
