Having two 2023/24 players on the list may be an indication that the start of this season is a bit of an outlier in general, especially given Guirassy has a higher goals per app rate (1.67) than Kane (1.55). It gets even more pronounced when you calculate by minutes played: Kane is averaging a goal every 57 minutes whilst Guirassy is scoring every 44 minutes. They have a very similar G/A rate, with Guirassy just edging it.
It will be interesting to see if both players maintain that same scoring rate of the first third of the season through the next 23 games.
