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.
