Thought I'd run some stats on Sheridan, Williams, and Krishna
The chart below shows Sheridan's stats in the Polish, Cypriot, and now A-leagues. Basically, he's expected to score ~0.38 goals per game, and make 0.14 assists. (Obviously have to make an assessment of how these leagues compare with A-league)
I've just got this season's data for Williams and Krishna. They both show that expected goals is a bit less than actual goals for both this season, which could indicate a bit of luck, or also that they're managing to score in positions that most other players couldn't. To me, looking at these, I'd think Sheridan should start.
Blue bar is expected goals. Orange is actual goals. Grey is assists.

Thanks for your work in putting this together. However, it shows Krishna and Williams stats in a Phoenix environment, while for Sheridan this is based on teams where he was surrounded by players unrelated to those he is now playing with. We cannot readily expect him to just repeat the same outcome when working alongside completely new people so early on.
Both Krishna and Williams have overachieved so far in terms of goals (based on the graph). But we do not know if this is what Sheridan's role will be . He has, for example, produced a couple of excellent passes to Krishna in games against WSW and against CCM, but did not score (I am not sure if his passes would count as an assist for the above table). I would be keen to see this graph towards the end of the season and only related to Phoenix performances (for Sheridan). And I hope it'll show he will have overachieved.
Actually, getting outplayed quite a bit these days
