For me he doesn’t look like a natural winger, looks more like a division twos Mo Salah type, had 6 assists last season with 10 goals I believe? And of the 6 assists non were quality crosses.
Looks like he has real pace and also two feet though predominately right footed, looks adept at cutting in from the left or playing on the right, even filled in up front on occasion from what I can gather.
Probably get stick for this but if we signed him would prefer us to play like Liverpool, having Hemmings in the firminio role, our full backs would offer that natural width.
But that offers no space for Dennis, but I do think that is his best position, and from what I have seen of Hemmings and heard of him possibly would suit him also.
