These stats are completely meaningless, it was a completely different team and set of players.
I like Gnonto and think he is better than of the some of the players he has but the assist thing is a myth, as it 100% depends on the striker you have.
People said the same the last few windows when 2 summers ago I said we don't have the players who create in this team, we then went and finished 19th for chances created and survived relegation by the skin of our teeth. And last summer when vast majority were thrilled with our summer window - I repeatedly said we didn't have any players with any proven credentials of scoring more than 5 league goals a season, or providing assists/chances etc and how our team was less equipped to survive relegation last season than the season before. Look what happened.
The point is - we can't expect players who haven't ever scored goals regularly to suddenly start scoring them.
I've not seen Gnonto play, but if he comes in we need him to at least replace Gray's goals - which to be fair, isn't a big challenge but we need more creativity and composure... goals in that final third. A lot more goals. Otherwise start stocking up on your blood pressure medications for another season.
