Sorry to revive a dead thread but the difference between assists on transfermarkt and Fbref etc has got me wondering if there's a place where we can see a per game box score type thing for assists? On the a-league match centre they have the goals and some other stats but not assists listed. But is there somewhere else that you can go to a specific game and see who got the assists in that game?
FotMob (website + app) & Sofascore - Football (app) are good for this.
Can select individual matches by visiting the 'club' page or searching for what you want through the search bar. Or you flick through the playing squad and filter what you want by selecting any player you choose.
The following are screengrabs from both platforms, both showing Kosta's rich vein of form earlier in the season.

Sofascore
For each individual match on both platforms you can click on the team names to bring up all stats from a particular game - formations, player lists, real time ticker of match action and all the stats.
FotMob is my go to, but to each their own.
