Sparta has an elo 112 points higher, thats quite a jump. So performance needa to be adjusted for that
But apart from end product early in the season segacic has really struggled to contribute. Very weak off the ball in both finding space and making defensive contributions. Thats still spectacular at his age by recent aussie standards. Kuols end product is worse but has had some moments on and off the ball when ive watched them. I think they are pretty similar quality with difference strengths and weaknesses and its hard to tell who will have a better career at this stagr
